Find the value of x.
A
7x + 10
с
В
00
9x - 2
D

6

Step-by-step explanation:

AB = BD

so, 7x + 10 = 9x -2

or, 10 + 2 = 9x -7x

or, 12 = 2x

or, 6=x

Therefore, x=6

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)
