Answer:

D) The rectangle undergoes a dilation by a scale factor of 0.5.

Step-by-step explanation:

A translation is only a slide; it does not change the size of a figure.

A reflection creates a mirror image; it does not change the size of a figure.

A rotation turns a figure; it does not change the size of a figure.

A dilation is a stretch or shrink, which by definition changes the size of a figure.

A dilation by a factor greater than 1 will stretch a figure, and a dilation by a factor less than 1 (but greater than 0) will shrink a figure.  Since we want a reduction in size, we want a shrink; this means out of all of our options, the only correct one is a dilation by a factor of 0.5.

Kazeer [188]

Answer:

The solutions are given below:

Step-by-step explanation:

x(x-3)+4(x²+2)

= x²-3x+4x²+8

= x²+4x²+8-3x

= 5x²+8-3x

2(a+5)-3(a+7)

= 2a+10-3a-21

= 2a-3a+10-21

= -a-11

xy(x²yz-xy²z+xyz²)

= x³y²z-x²y³z+x²y²z²

-4(a²-2a+8)

= -4a²+8a-32

7x+16=8x+15 solve for x and y
elena55 [62]

Answer:

x = 1

Step-by-step explanation:

7x + 16 = 8x + 15

<u>Step 1</u> : Subtract 15 on both sides

7x + 16 - 15 = 8x

7x + 1 = 8x

<u>Step 2</u> : Subtract 7x on both sides

1 = 8x - 7x

1 = 1x

x = 1
