The graph of a quadratic function is shown below. An equation that represents the function could be A - q(x) = -0.5(x - 15)² + 25

B - q(x) = 0.5(x - 15)² + 25

C - q(x) = -0.5(x + 15)² - 25

D - q(x) = 0.5(x + 15)²-25

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)

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
