Afarmer has 100 m of fencing to enclose a rectangular pen. which quadratic equation gives the area (a) of the pen, given its width (w)?
1. a(w) = w2 – 50w
2. a(w) = w2 – 100w
3. a(w) = 50w – w2
4. a(w) = 100w – w2

step-by-step explanation:

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: 1 + 1 = 11
