Answer:
y = 3x + 13
Step-by-step explanation:
The equation of a line is also known as slope-intercept form.
Slope-intercept form is y = mx + b where m is the slope and b is the y-intercept.
To put an equation in slope-intercept form, we need the slop and the y-intercept.
In this case, we already have the slope which is 3.
So far, we have y = 3x + b
Now, we need to find the y-intercept.
Since you already have a point, we can plug in the x and y values from the point, into the equation.
10 = 3(-1) + b
Now, we can solve for b.
10 = -3 + b
Add three on both sides so it becomes:
13 = b
13 is the y-intercept
y = 3x + 13
What is the surface area of this square pyramid?

What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
To find the surface area of this square pyramid
Now, We know that;
the surface area of this square pyramid is,
⇒ SA = B + 1/2 pl
Where, B represents the area of the base. p represents the perimeter of the base. l represents the slant height.
Now, We get;
B = 12 x 8
B = 96
p = 2 (12 + 8)
p = 40
l = 10
Thus, the surface area of this square pyramid is,
⇒ SA = B + 1/2 pl
⇒ SA = 96 + 1/2 x 40 x 10
⇒ SA = 96 + 200
⇒ SA = 296 cm²

What is the slope of the line that passes through the points (4, 8)(4,8) and (8, 6)(8,6)? Write your answer in simplest form.
Using linear function concepts, it is found that the slope of the line that passes through points (4,8) and (8,6) is of -0.5.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.The line goes through points (4,8) and (8,6), hence when x changes by 4, y changes by -2, and the slope is given by:
m = -2/4 = -0.5.

The profit (p) a baker earned, in dollars, is proportional to the number of muffins (m) sold. This equation represents this relationship.
P = 0.75m
enter the profit earned for each muffin sold.
P = 0.75m represents the proportional relationship, therefore, the profit earned for each muffin sold is: $0.75.
What is Proportional Relationship?If two variables, i.e. P and m are directly proportional to each other, the relationship between them can be represented as P = km, where k is the constant.
Given that P = 0.75m represents the proportional relationship between the profit earned and muffins sold, the constant, k, is 0.75, which is the profit earned for each muffin sold.

Answer:
Option (2). 14 m
Step-by-step explanation:
Formula to get the area of a circle 'A' =
where r = radius of the circle
Given in the question,
Area of the circle = 153.86 square meters
By putting the values in the formula,
153.86 = πr²
r = [tex]\sqrt{\frac{153.86}{\pi } }[/tex]
r = [tex]\sqrt{49}[/tex]

- A jar contains 55 quarters and dimes. The total value of the coins is $8.50. Find the
number of quarters and dimes in the jar.
Answer:
20 quarters and 35 dimes.
Step-by-step explanation:
Let number of quarters = q
Therefore number of dimes = 55 - q
By condition, q * 25 + (55 - q) * 10 = 850 [all converted to cents]
25q + 550 - 10q = 850
25q - 10q = 850 - 550
15q = 300
q = 300/15 = 20
Therefore, number of quarters = 20
and number of dimes = 55 - 20 = 35

Explain how you would find the coordinates of the image (5, 2) if it was reflected over the x-axis and then that image was reflected over the y-axis what would be the end result?
Answer:
the end result is (-5 , -2)
Step-by-step explanation:
Let A’ be the image of A(5 ,2) by reflection over the x-axis
and Let A’’ be the image of A’ by reflection over the y-axis
Formula:
➽if we reflect a point M of coordinates (x , y) over the x-axis we get the image point M’ of coordinates (x , -y)
➽ if we reflect a point N of coordinates (z , t) over the y-axis we get the image point N’ of coordinates (-z , t)
_____________________________
According to the formula :
A(5,2) ———-> A’(5 , -2) ———-> A’’(-5 , -2)
Answer: To find the image after a reflection over the x-axis, I would negate the y-coordinate. To find the image after a reflection over the y-axis, I would negate the x-coordinate. So, reflecting the point (5, 2) over the x- and y-axis, I would get (–5, –2).

Andrea bough a bucket of colored chalk. The list below shows the fraction of each color of chalk in the bucket. 2/6 are yellow, 5/12 are blue, and 3/12 are green. Andrea told Michelle that less than 1/2 the chalk in the bucket is blue. Michelle said she is mistaken. Who is correct? Explain why you chose your answer.
Given the fraction of each colored chalk, Andrea is right that less than 1/2 the chalk in the bucket is blue.
How to solve fractions?Yellow = 2/6Blue = 5/12Green = 3/12Total = 2/6 + 5/12 + 3/12
= (4+5+3) / 12
= 12/12
= 1
Fraction of blue : Total chalk
= 5/12 : 1
Blue = 5/12 ÷ 1
= 5/12 × 1/1
= 5/12
= 0.42
So,
1/2 = 0.5
Therefore, Andrea is right that less than 1/2 the chalk in the bucket is blue.
