With 11 and 12 due tomorrow alos explain how u got the answer

11. X=7

For 12, im not sure but I think it's

Step-by-step explanation:so for 11 I just divided 70 by 10 cuz to find the area of a rectangle or square you multiply the width by length. For 12 I think it's 5 because I know that you multiply the width by length then divide it in half.

Also what grade are you in?

what's that

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)
