Question

If line segment A'B'= 10, and it went through a dilation transformation with a scale factor of 1/5, what is line segment AB?
Select one:
a. 50
b. 20
c. -5
d. 2

Answer 1

x = length of AB


(length of AB)*(scale factor) = length of A'B'

x*(1/5) = 10

x = ??

Answer 2

x=20?? @jim_thompson5910

Answer 3

hint: multiply both sides of x*(1/5) = 10 by 5
