If x=-2 and y=/12, then 2(3×3 +2y2)=

114

Step-by-step explanation:

Plug in the numbers into the equation

2(3*3+2*12*2)

then solve in the parenthesis (PEMDAS)

2(9+48)

2(57)

then multiply by 2

114

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)
