Which algebraic representation shows a reduction?

(x, y) → (-3x, y)

(x, y) → (x - 3, y - 3)

(x, y) → (-3x, -3y)

(x, y) → (12 x, 12 y)

D. (x, y) →

Step-by-step explanation:

A dilation is a transformation which reproduces an image of the same shape as the original, but might be of a different size.

When the dilation produces a smaller image is called a reduction.

Mathematically, a reduction occurs whenever the scale factor is between 0 and 1.

Out of the options, the only one that has a scale factor less than one is:

(x, y) →

Since the scale factor is 1/2 which is less than 1.

All other options are not reductions.

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
