153
and the width is given by 4
68
, which radical expression represents the perimeter of the rectangle?
a) 6
34
b) 14
17
c) 28
17
d) 32
17

answer: d. $20

step-by-step explanation:

just took the test

b. x + 1

step-by-step explanation:

i'am smart

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
