Edgar is constructing a rectangular play area against an exterior wall of his house for his guinea pig. He uses 60 feet of fencing material to enclose 3 sides of the play area. Write an equation to represent l, the length of the play area in feet, as a function of w, the width in feet. 

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)

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

answer:

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21  

-7 + ? = 21

-7 + 28 = 21

hope it
