Question

PLEASE HELP ME

What is the scale factor of this dilation?
1/2
2/3
3/4
3/2

Answer 1

`(3)/(4)`

Explanation:

To determine the scale factor calculate the ratio of the corresponding sides of the image to the original, that is

scale factor =
`(Z'Y')/(ZY)` =
`(9)/(12)` =
`(3)/(4)`

Answer 2

3/4

Explanation:

XZ = 8 and X'Z' = 6

To find the dilation you have to divide them

6 ÷ 8 = 3 ÷ 4 = 0.75
