Which scale factors produce a contraction under a dilation of the original image? select each correct answer. −2 −1/2 1/2 2 select 2 answers 20 points

−2  and −1/2.

Step-by-step explanation:

A dilation is a transformation of a geometric image that is known to change its size but not the shape.

The size of the figure basically depends on the scale factor (k) .

When k >1 , then there would be expansion.

When k<1 , then there would be contraction.

When k=1 , then no change in size.

i.e. For contraction , the scale factor (k) must be negative.

From the given options , the scale factors produce a contraction under a dilation of the original image would be  −2  and −1/2.

Hence,the correct answers are : −2  and −1/2.

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
