Part A:
An isometric transformation is a type of transformation where the original shape and size of the pre-image is not altered in the image.
To show that the translation was an isometric transformation, we show that the distance between any two points in the pre-image is equal to the distance between the corresponding points in the image.
Consuder, line AB, the distance between point A and point B is given by:

The distance between point A' and point B' in the image is given by:

Similarly checking other points of the pre-image against the corresponding points of the image shows that the size of the pre-image is preserved in the image.
Part 2:
The translation that maps the triangle ABC onto its image are:
Triangle ABC was shifted 4 units to the right.
Triangle ABC was shifted 4 units up.
5r + 6s = 53
25r + 3s = 49
Meaning of simultaneous is to solve by elimination
Multiply the equation 2 by -2
-2( 25r + 3s = 49)
-50r – 6s = -98
Then add the two equation to eliminate s, so the resulting equation is:
-45r =-45
r = 1
substitute r = 1 to equation 1
5(1) + 6s = 53
6s = 53 – 5
6s = 48

Answer: C. Jaclyn did not make an error. I just worked on this on e2020
Answer:
y = 25
Step-by-step explanation:
Given y = kx and k = 5 then
y = 5x ← equation of variation
When x = 5 , then
y = 5 × 5 = 25
Answer:
g(f(x)) means that the x of the g function is the f(x) function, if that makes sense.
so you do 8(x-10)-5
8x-80-5
8x-85
