A: y=2x+3. This is an equation for the linear relationship in slope-intercept form. The equation states that the value of y is equal to the slope of the line, 2, multiplied by the value of x, plus 3.
What is slope?Slope is a measure of the steepness of a line. It is the ratio between the vertical change in a line (change in y-values) over the horizontal change in the same line (change in x-values). It is also referred to as the rate of change, as it is a measure of how quickly the value of y changes with respect to the x-value.
This equation is used to describe a straight line that has a constant rate of change between two variables. This equation can be used to determine the slope, y-intercept, and x-intercept of a line.
The slope, which is the coefficient of x in the equation (2 in this case), is the rate at which y changes with respect to x. It is the rise over run, or the change in y over the change in x. The y-intercept is the value of y when x is equal to 0 (in this case, it is 3). The x-intercept is the value of x when y is equal to 0 (in this case, it is -3/2).
This equation is often used to represent a linear relationship between two variables, such as the amount of money a person earns in relation to the number of hours they work.

How do I get domain for (x-7)(x-1) over (x+3)(x-1)
Answer:
To find the domain of the function f(x) = (x-7)(x-1)/(x+3)(x-1), we need to consider the values of x that make the denominator zero since division by zero is undefined.
In this case, the denominator (x+3)(x-1) is zero when x = -3 and x = 1. Therefore, we need to exclude these values from the domain.
So, the domain of f(x) is all real numbers except x = -3 and x = 1.
In interval notation, we can write the domain as (-∞, -3) U (-3, 1) U (1, ∞).
20 POINTS ANSWER FOR BRAINLIST SHOW WORK
Subtract. Express the answer in standard Form.
(8s ^2 − 3s − 3) − (−4s ^2 + s − 13)
Answer:
To subtract the second polynomial from the first, we need to distribute the negative sign to all terms inside the second set of parentheses, and then combine like terms:
(8s^2 - 3s - 3) - (-4s^2 + s - 13)
= 8s^2 - 3s - 3 + 4s^2 - s + 13 (distributing the negative sign)
= 12s^2 - 4s + 10 (combining like terms)
The resulting polynomial is already in standard form because the terms are arranged in descending order of degree. Therefore, the final answer in standard form is:
12s^2 - 4s + 10
The perimeter and the length of the base of an isosceles triangle are 25cm and 9cm respectively. Calculate the area of the triangle. (Ans: 29.76cm²)
Answer:
Let's denote the length of the equal sides of the isosceles triangle by "x". Then the perimeter of the triangle can be expressed as:
Perimeter = 2x + 9
But we also know that the perimeter of the triangle is 25cm, so we can set these two expressions equal to each other and solve for x:
2x + 9 = 25
2x = 16
x = 8
Therefore, the length of each of the equal sides is 8cm. Now, we can use the formula for the area of a triangle:
Area = (base × height) / 2
Since the triangle is isosceles, we know that the height is also the perpendicular bisector of the base, dividing it into two equal parts of length 4.5cm each. Now we can find the height of the triangle using the Pythagorean theorem:
h² + 4.5² = 8²
h² + 20.25 = 64
h² = 43.75
h ≈ 6.61
Substituting these values into the formula for the area of the triangle, we get:
Area = (9 × 6.61) / 2
Area ≈ 29.76 cm²
Therefore, the area of the isosceles triangle is approximately 29.76 cm².
PLEASE HELP....Dilations
Okay, just think of dilations as scaling the object bigger or smaller. You are just multiplying all points on the shape by a common scalar.
The only other thing is a negative dilation reflects the shape over the origin (which is quite intuitive cause you negate all the coordinates).
Now for question 1 your just trying to find the scale factor given an original point and a dilated point. Since all points are multiplied by the same factor,
(-3,6)x = (-4,8)
x=4/3
For the second question, just check points to see if all follow the same dilation scale factor. For our purposes it suffices to just check the each vertex.
(1,1) -> (2,2) so the scale factor must be 2
(1,4) -> (2,8) good
(5,1) -> (10,2) good
(5,4) -> (10,8) good
So, this transformation describes a dilation. The scale factor is 2.
Natasha worked for part of the year before receiving a raise in her hourly rate of pay. The graph below shows the amount of money she has made this year and the hours she has worked since she received the raise. What was the initial amount of money Natasha made?
Answer:
Unfortunately, I cannot see the graph you are referring to since we are communicating through text. However, based on the information given, we can make some general observations.
We know that Natasha received a raise in her hourly rate of pay at some point during the year. Before the raise, she earned some initial hourly rate of pay. Let's call this initial rate of pay "x". Let's also assume that she worked for "h" hours before receiving the raise, and "k" hours after receiving the raise.
We can write an equation to represent the total amount of money she made this year:
Total amount of money = (initial hourly rate of pay x number of hours worked at the initial rate) + (new hourly rate of pay x number of hours worked at the new rate)
Using the variables we defined earlier, we can write:
Total amount of money = (x × h) + ((x + y) × k)
where y is the increase in her hourly rate of pay after the raise.
We also know that she earned a certain amount of money before the raise. Let's call this amount "M". This means that:
M = x × h
Solving for x, we get:
x = M/h
Substituting this expression for x into the first equation, we get:
Total amount of money = (M + yh) + ((M/h + y) × k)
We don't know the values of M, y, h, or k, so we cannot determine the initial hourly rate of pay x or the total amount of money Natasha made this year. However, we have set up an equation that can be used to solve for these values if we have more information.

A paper drinking have in the shape of a cone has a height of 10 cm in a diameter of 8 cm which of the following is closest to the volume of the cup in cubic centimeters
Step-by-step explanation:
The volume of a cone can be calculated using the formula:
V = (1/3)πr^2h
where r is the radius of the base, h is the height of the cone, and π is a constant approximately equal to 3.14.
In this case, the diameter of the base of the cone is 8 cm, which means the radius is half of that, or 4 cm. The height of the cone is given as 10 cm. Substituting these values into the formula, we get:
V = (1/3)π(4 cm)^2(10 cm)
V ≈ 167.55 cubic centimeters
Therefore, the volume of the paper drinking cone is closest to 167.55 cubic centimeters.

Review the graph of a piecewise function.
The range of the function is the set of all real numbers greater than or equal to -2, because the lowest possible value of the function is -2, which occurs at x = 2.
What is a piecewise function ?
A piecewise function is a function that is defined by different equations on different parts of its domain. The graph of a piecewise function consists of several distinct parts, each corresponding to a different equation.
The graph shown is an example of a piecewise function. The function is defined using different equations on different intervals of the domain.
On the interval from negative infinity to negative 2, the function is defined by the equation y = 2. This means that the value of the function is always 2 on this interval, regardless of the value of x.
On the interval from negative 2 to 2, the function is defined by the equation y = -x. This means that the value of the function is equal to the negative of x on this interval.
On the interval from 2 to positive infinity, the function is defined by the equation y = 2. This means that the value of the function is always 2 on this interval, regardless of the value of x.
At the point x = -2, the function experiences a discontinuity, because the two equations that define it have different values at this point. The function is not differentiable at this point, because it does not have a well-defined tangent line.
The domain of the function is the set of all real numbers, because there are no restrictions on the values of x that are allowed.
Therefore, The range of the function is the set of all real numbers greater than or equal to -2, because the lowest possible value of the function is -2, which occurs at x = 2.

The linear function can be written as:
f(x) = -x/3 + 17/3
How to find the linear function?A general linear function can be written as:
f(x) = ax + b
Where a is the slope, and b is the y-intercept.
If we know two points on the line (x₁, y₁) and (x₂, y₂), then the slope of the linear function is:
a= (y₂ - y₁)/(x₂ - x₁)
Here we know the pairs:
f(-4) = 7
f(5) = 4
So we have the points (-4, 7) and (5, 4), then the slope is:
a = (4 - 7)/(5 + 4) = -3/9 = -1/3
Then we can write:
f(x) = -x/3 + b
now we can use one of the given points, like f(5) = 4, replacing that there we will get:
4 = -5/3 + b
4 + 5/3 = b
12/3 + 5/3 = b
17/3 = b

dimension measures 6 meters. Use labeled sketches and equations to model and
solve this problem. Show your work. Label your answer with the correct units.
The perimeter does indeed equal 254 meters, which confirms that our answer is correct.
What in mathematics is the perimeter?Any two-dimensional closed shape's perimeter is defined as the entire distance encircling it. The perimeter of a rectangle, such as the following: Square perimeter equals the sum of its four edges. Rectangle perimeter equals the sum of its four edges.
Let's call the rectangle's unidentified size x.
P = 2l + 2w, where l is the length and w is the breadth, gives the perimeter of a rectangle.
So that we can create an equation:
254 = 2l + 2(6)
Simplifying the right side:
254 = 2l + 12
Subtracting 12 from both sides:
242 = 2l
Dividing both sides by 2:
121 = l
Consequently, the rectangle's undetermined measurement (length) is 121 metres.
We can compute the perimeter using both variables to confirm our conclusion:
P = 2(121) + 2(6) = 242 + 12 = 254

What is Quadratic equation?
A quadratic equation is a second-degree polynomial equation in a single variable of the form ax^{2} + bx + c = 0, where a, b, and c are constants and x is the variable. The highest exponent of the variable in a quadratic equation is 2, and the equation can be written in standard form, where the coefficient of the squared term (a) is not equal to zero.
The given expression is:
5x² - √3x + 2
This is a quadratic expression in the variable x, which means that it can be written in the form of ax² + bx + c, where a, b, and c are constants. In this case, we have:
a = 5
b = -√3
c = 2
We can use the quadratic formula to find the roots of this expression:
x = [-b ± √(b² - 4ac)] / 2a
Now, putting the values of a, b, and c, we get:
x = [-(-√3) ± √((-√3)² - 4(5)(2))] / 2(5)
Now, Simplifying the expression under the square root, we get:
x = [√3 ± √(-71)] / 10
Since the expression under the square root is negative, there are no real roots to this equation. Therefore, the expression 5x² - √3x + 2 has no real solutions.

What is a graph, exactly?A graph is characterized by a mathematical construct that connects a collection of points to express a specific function. It establishes a pairwise connection between the objects. The graph was made up of nodes (vertices) connected by edges (lines).
We can see that for any two points on a line, the difference between their y- and x-coordinates is always the same. Let's determine this difference for the ordered pairs provided:
(1, 7) - (0, 4) = (1 - 0, 7 - 4) = (1, 3)
(2, 10) - (1, 7) = (2 - 1, 10 - 7) = (1, 3)
As we can see, the difference between the x-coordinates and y-coordinates of any two consecutive points is the same, i.e. 3. Therefore, we can check which of the points given in the options has a difference of 3 between its x-coordinate and y-coordinate.
A. (5, 19): Difference = 19 - 5 = 14
B. (-1, 1): Difference = 1 - (-1) = 2
C. (-3, -5): Difference = -5 - (-3) = -2
D. (-7, -19): Difference = -19 - (-7) = -12
So, we see that option A has a difference of 14 between its x-coordinate and y-coordinate, which is not equal to 3. Therefore, the point (5, 19) would NOT be found on the line. The correct answer is A. (5, 19).
