Please help me

Step-by-step explanation:

Given

x² = x + 12

x² - x - 12 = 0

x² - ( 4 - 3)x - 12 = 0

x² - 4x + 3x - 12 = 0

x ( x - 4) + 3 ( x - 4) = 0

( x - 4 ) ( x + 3) = 0

Either

x - 4 = 0

X= 4

Or

x + 3 = 0

x = -3

Therefore x = - 3 , 4

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)
