Find the scale factor and the ratio of the perimeters for two regular pentagons with areas 144 in² and 36 in² *
scale factor is 2:1 and perimeter ratio is 4:1
scale factor 2:1 and perimeter ratio is 2:1
scale factor is 4:1 and perimeter ratio is 2:1
scale factor is 4:1 and perimeter ratio is 4:1

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
