What is the absolute value of the
following numbers:
5, -6, 2, -9,

5, 6, 2, 9

Step-by-step explanation:

Absolute value is the units away from 0 that a number is, meaning that it is always positive. So, 5 is 5 units from 0, -6 is 6 units from 0, 2 is 2 units from 0, and -9 is 9 units from 0.

−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.
