Question

What scale factor was used to dilate STUV to S’T’U’V?

A. 0.20
B. 0.50
C. 0.25
D. 0.75

Answer 1

Answer: C. 0.25

Step-by-step explanation:

Large Shape: S (-4, 12) T (2, -4) U (6, -8) V (-12, -8)

Small Shape: S (-1, 3) T (0.5, -1) U (1.5, -2) V (-3, -2)

For the smaller shape the distance between V and U is 4.5

For the larger shape the distance between V and U is 18

So when you divide
`(4.5)/(18)` you should get 0.25

S:
`(-4)/(-1)=4`
`-4 *0.25=-1`

T:
`(2)/(0.5)=4`
`2*0.25=0.5`

U:
`(6)/(1.5)=4`
`6*0.25=1.5`

V:
`(-12)/(-3) =4`
`-12*0.25=-3`

I hope this helps
