use triangle ABC with vertices A (3,4) B(1,6) and C(1,1). translate triangle ABC 5 units left and 3 unts down whats the B coordinate
Answer:
(6,3). P
Step-by-step explanation:
Hello there my friend ;D
When we are talking about translation, it is really simple. Let me simplify it for you with the formulas. When they are asking you do move left or right, that means the x coordinate will moved (‘a’ will be the units they ask you to move) If they are asking you to move LEFT: (x,y) —> (x-a, y). If they are asking you to move RIGHT: (x,y) —> (x+a, y). Now if they are asking you to move up or down, that mean the y-coordinate will move (‘b’ will be the units they ask you to move) If they ask you to move UP: (x,y) —> (x, y+b). If they ask you to move DOWN: (x,y) —> (x, y-b). NOW, In our current problem, they are asking what is B’ coordinate, B was (1,6). B will be translated 5 units LEFT and 3 units DOWN. Now that I have already explained, (1+5, 6) —-> (6, 6). (Note: ALWAYS do x before y). Then (6, 6-3) —> (6, 3). SO, the answer is (6,3).

How much does a cat way on the moon
Answer:
Since weight is directly dependent on the acceleration of gravity, things on the Moon will weigh only 16.6% (≈ 1/6) of their weight on Earth.
Step-by-step explanation:
Being that the moon has a gravitational force of 1.622m/s2, we multiply the object's mass by this quanitity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon.

brainy plot and labels points P (-5/2), Q (2 3/4), R(1.25), and S(-3.5) on the number line
Answer:
Step-by-step explanation:
To plot points P (-5/2), Q (2 3/4), R(1.25), and S(-3.5) on a number line, we can simply draw a horizontal line and mark off the positions of the points. The numbers on the number line will represent the values of the x-coordinates of the points.
[asy]
unit size(1cm);
draw((-7,0)--(5,0));
draw((-7,0)--(-7,1)--(5,1)--(5,0)--cycle);
dot("$P$", (-5/2,0), S);
dot("$Q$", (2 3/4,0), S);
dot("$R$", (1.25,0), S);
dot("$S$", (-3.5,0), S);
[/asy]
On the number line, point P is located at -5/2, point Q is located at 2 3/4, point R is located at 1.25, and point S is located at -3.5.
Compute the smallest base-10 positive integer greater than 5 that is a palindrome when written in both base 2 and 4.
The smallest base-10 positive integer greater than 5 that is a palindrome when written in both base 2 and 4 is 11.
To compute this, first convert 5 to binary and base-4:
5 in binary: 101
5 in base-4: 11
Since 11 is the same in both bases, the next number that would be a palindrome in both bases is 11.
To find the base 10 number of this palindrome, we convert 11 from binary and base-4 to base 10:
11 in binary: 1011
11 in base-4: 111
Therefore, the smallest base-10 positive integer greater than 5 that is a palindrome when written in both base 2 and 4 is 11.

Consider the following 8 numbers, where one labelled x is unknown. 28, 39, 21, x , 33, 38, 2, 45 Given that the range of the numbers is 57, work out 2 values of x
The needed two values of x are: 59 and -12.
The difference between a sequence's maximum value and minimum value is referred to as the sequence's range.
A sequence's range is just a set that identifies the sequence. The set x1, x2, x3, and so forth is typically used to describe the range; it is also written as xn; n = 1, 2, 3,...
Given sequence of 8 numbers as: 28, 39, 21, x , 33, 38, 2, 45
Given range of above sequence: 57
Since the value x can assume any value, it have option to be minimum value in the sequence or maximum value in the sequence such that the range remains at 57.
Case 1: x as minimum value of given sequence:
If so, then the maximum value is 45. Then-
range = maximum value - minimum value
57 = 45 - x
x = -12
Case 2: x as maximum value of the given sequence:
If so, then the minimum value of the sequence is 2. Then-
range = maximum value - minimum value
57 = x - 2
x = 59
Thus, the needed two values of x are: 59 and -12.

The ratios equivalent to 2:14 are 3:21 and 16:112. Option A &C
What is equivalent ratios?Equivalent ratios are the ratios that are the same when we compare them. Two or more ratios can be compared with each other to check whether they are equivalent or not. For example, 1:2 and 2:4 are equivalent ratios.
2:14 = 2/14
Reducing 2/14 to the lowest terms = 1/7
2:14 is equivalent to 1:7
3:21 = 3/21 = 1/7
Reducing 3/21 to the lowest terms = 1/7
3:21 is equivalent to 1:7
1:2 = 1/2
1:2 is not equivalent to 1:7
16:112 = 16/112 = 1/7
Reducing 16/112 to the lowest terms = 1/7
16:112 is equivalent to 1:7

Complete the square to write each equation in vertex form. Then, state whether the vertex is a minimum or a maximum and give its coordinates.
Answer:
a) y(x) = (x + 2)^2 -2
b) minimum
c) (-2, -2)
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
Given
y = x² + 4x + 2
(a)
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² + 4x
y = x² + 2(2)x + 4 - 4 + 2
y = (x + 2)² - 2
(b)
Since a = 1 > 0 then vertex is minimum
(c)
(h, k ) = (- 2, - 2 ) ← coordinates of vertex

Based on the table, an equation of the linear relationship in slope-intercept form include the following: A. y = 2x − 8
What is the slope-intercept form?Mathematically, the slope-intercept form of a line can be calculated by using this equation:
y = mx + c
Where:
m represents the slope.x and y are the data points.c represents the y-intercept.Next, we would determine the slope of the data points in this table as follows;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
Slope, m = (-6 - (-8))/(1 - 0)
Slope, m = 2/1
Slope, m = 2.
At point (0, -8), an equation of this line can be calculated in slope-intercept form as follows:
Note: The y-intercept is equal to -8.
y = mx + c
y = 2x + (-8)

What is simplified form of the expression?
If a fraction's top and bottom have only the number one in common, then it is expressed in its simplest form. The top and bottom cannot be divided further and remain whole numbers, in other words. The phrase "lowest terms" is another term for the simplest form.
Consider, the given expression
[tex]\frac{(\frac{1}{x^2}-\frac{2}{y} )}{y-2x^2}[/tex]
We have to find the simplified form of the given expression.
Taking cross multiplication of numerator of the above fraction.
[tex]\frac{(\frac{y-2x^2}{x^2y} )}{y-2x^2}[/tex]
Using: [tex]\frac{(\frac{a}{b} )}{c} = \frac{a}{b}*\frac{1}{c}[/tex]

A square and an equilateral triangle are joined to form the polygon shown what is the sum of the interior angles of the polygon 240 degrees 360 degrees 420 degrees 540 degrees
Answer:
540°
Step-by-step explanation:
An equilateral triangle has 3 interior angles of 60°
A square has 4 interior angles of 90°.
When the images are joined, two vertices of each figures are joined together, such that these angles will have now a measure of:
60° + 90° = 150°
Then this figure has:
one angle of 60°
two angles of 150°
and two angles of 90°
(the image below illustrates this situation)
The sum of the interior angles is:
S = 60° + 2*150° + 2*90° = 540°

Reason Abstractly Determine if the

response.
The point (1, r) on the graph of a proportional
relationship shows the unit rate r.
Yes, the statement is true. If a proportional relation has the point (1, r), then r is the unit rate.
Is the statement true or false?Here we have the following statement:
"The point (1, r) on the graph of a proportional relationship shows the unit rate r."
First, remember that a proportional relationship between two variables x and y can be written as:
y = k*x
There k is what we call the constant of proportionality or the unit rate.
If we evaluate that equation in x = 1, we will get:
y = k*1
y = k
Then we have the point (1, k).
In this case, we know that our proportional relation has the point (1, r), comparing this with the case above, we can see that r is the unit rate of the proportional relation.
So the statement is true.

The equation of a line is:

We are told that the slope is 4 which is also gradient, meaning that M=4
Now we are left with:
Y=4x+c
There are two ways to get C:
1. We know that C represents the y-intercept so immediately we can conclude that C=-1
2. You can work it out by substituting the coordinate for the X and Y value:
