Determine whether each scale factor produces an expansion or a contraction under a dilation of the original image

blondinia [14]

Answer:

see the explanation

Step-by-step explanation:

we know that

If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image

If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image

Verify each value

1) -4

$\left|-4\right|=4$

$4> 1$

therefore

The dilation produces an expansion of the original image

2) 0.25

$\left|0.25\right|=0.25$

$0.25 < 1$

therefore

The dilation produces a contraction of the original image

3) -2/3

$\left|-2/3\right|=2/3$

$2/3 < 1$

therefore

The dilation produces a contraction of the original image

4) 2.3

$\left|2.3\right|=2.3$

$2.3 > 1$

therefore

The dilation produces an expansion of the original image

Will the opposite of a number always, sometimes, or never be greater than the number itself? Explain your reasoning. Provide an

aksik [14]

Step-by-step explanation:

The negative of a number may sometimes be greater than the number itself.

The negative of a negative number is positive which will give a greater number than the number itself. But the negative of a positive number is negative which is smaller than the number itself

Let us take a few examples

-(-1) = 1, 1>-1

-(1) = -1, 1>-1
