Answer: rotation can be expressed as the composition of two reflections. A composition of reflections over two parallel lines is equivalent to a translation. Example: Given a || b, and pre-image ΔABC, where parallel lines are vertical. The composition of reflections over two intersecting lines is equivalent to a rotation. A composition of transformations is a combination of two or more transformations, each performed on the previous image. A composition of reflections over parallel lines has the same effect as a translation (twice the distance between the parallel lines). i hope this helps.

The equation y = 3x + 1.25 represents the cost, y, in dollars, of bowling x games and renting a pair of bowling shoes. Shoes are rented for a flat rate that does not depend upon the number of games bowled. What does the slope of this equation represent? *
Answers
Answer:
Cost per game
Step-by-step explanation:
Given
[tex]y = 3x + 1.25[/tex]
Required
What does the slope represent?
First, we need to determine the slope
A general equation is of the form
[tex]y = mx + b[/tex]
Where
[tex]Slope = m[/tex]
By comparing:
[tex]y = mx + b[/tex] to [tex]y = 3x + 1.25[/tex]
[tex]m = 3[/tex]
Hence, the slope is 3
From the question we understands that a certain amount is paid per games.
This amount is represented by the rate or slope.

Angle 8 = 83
Angle 5 = 180 -83 = 97
Step-by-step explanation:
Check: Just an example to check using Co- interior angles
Angle 2 + Angle 5 = 180 degrees
83 +97 = 180 degrees
180 degrees = 180 degrees
Therefore Angle 5 = 97 degrees and Angle 8 = 83 degrees

The line equation in slope-intercept form is:
[tex]y\:=-\frac{2}{5}x+4[/tex]
Hence, option D is true.
Step-by-step explanation:
Given the points
(0, 4)(5, 2)Finding the slope between the points
[tex]\left(x_1,\:y_1\right)=\left(0,\:4\right),\:\left(x_2,\:y_2\right)=\left(5,\:2\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{2-4}{5-0}[/tex]
[tex]m=-\frac{2}{5}[/tex]
As the y-intercept is obtained by setting the value x = 0.
As we know that when x = 0, the vale of y-intercept y = 4
so the y-intercept is b = 4.
As the slope-intercept form is
substituting the slope m = -2/5 and the y-intercept b=4
[tex]y = mx+b[/tex]
[tex]y\:=-\frac{2}{5}x+4[/tex]
Therefore, the line equation in slope-intercept form is:
[tex]y\:=-\frac{2}{5}x+4[/tex]
Hence, option D is true.

A truck can be rented from Company A for $130 a day plus 50.30 per mile. Company B charges 570 a day plus 50.70 per mile to rent the same truck. Find the
number of miles in a day at which the rental costs for Company A and Company B are the same.
Answers
Answer:
Not possible
Step-by-step explanation:
You use the formula y = mx + b to make equations for both situations then solve from there
Let x be miles driven
Company A:
y = 50.30x + 130
Company B:
y = 50.70x + 570
You solve by making the equations equal each other to figure out the variable (miles driven)
50.70x + 570 = 50.30x + 130
50.70x + 570 - 50.30x + 130 - 50.30x
0.4x + 570 - 570 = 130 - 570
0.4x = -440
x = -1100
Therefore there is no amount of miles you can drive for Company A and Company B to have the same rental costs

Answer:
y=(-3/4)+2
Step-by-step explanation:
Hello there! In order to solve this problem we will have to find the slope of the line and then use the point slope formula
Firstly, lets solve for the slope by finding the change in y over the change in x:
slope (m)= [tex]\frac{y2-y1}{x2-x1}[/tex]
We will plug in the values of the points given and find that:
slope (m)= [tex]\frac{-1-2}{4-0}[/tex]
this equals (-3/4)
from here we will use the point slope formula to find for the equation that the line passes through. You can use either point for this step, I will be using A(0,2).
Point-slope equation:
[tex]y-y1=m(x-x1)[/tex]
Plugging in values:
[tex]y-2=(\frac{-3}{4})(x-0)[/tex]
after isolating y we find that the equation is:
[tex]y=\frac{-3}{4} x+2[/tex]
