Please help :> Lacy has $600 set aside to build a rectangular exercise kennel for her dogs. She will buy fencing
material for $15/10 Because the side of an existing barn will be used for one of the sides of the
kennel, only three sides need to be fenced.
a.
Determine the dimensions of the kennel that will enclose the maximum area.
b. What area will be enclosed?

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)

the answer is a and d
