what scale factor would you use on the 14-inch by 21-inch rectangle to return it to its original 2-inch by 3-inch size

since you are trying to get the scaled copy smaller you need to instead of multiply by 7 multiply by 1/7

Step-by-step explanation:

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10
