Step-by-step explanation:
I will be glad to help you in the comments. I do need to know though, what is the class this is presented in? Is this algebra, or calculus? Depending on the class, we have different approaches.
Answer:
128
Step-by-step explanation:
The coordinates of A in the pre-image is (-1,2).
D0, 3(x,y) means (x,y) → (3x,3y)
A'(-3,6)
B'(-0.5, 8)
C'(2,6)
D'(1,3)
E'(-2,3)
The coordinates of the pre-image are multiplied by 3 resulting to the coordinates of the given image. So, we simply divide each value of x and y by 3 to get the coordinates of the pre-image.
A'(-3,6) → -3/3 = -1 ; 6/3 = 2 → A(-1,2)
