Whats is x2 - x - 12 = 0

x=-3 or x=4

Step-by-step explanation:

x2−x−12=0

Step 1: Factor left side of equation.

(x+3)(x−4)=0

Step 2: Set factors equal to 0.

x+3=0 or x−4=0

x=−3 or x=4

answer: c i think

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
