y = -2x² + 920x - 84168

suppose: the equation of the parabola is y = ax² + bx + c

because the parabola passes through (126,0); (134,3200); (334,0)

=> we have the equations:

126².a + 126b + c = 0

134².a + 134b + c = 3200

334². a + 334b + c = 0

⇒ a = -2

    b = 920

    c = -84168

=>  the equation of the parabola is y = -2x² + 920x - 84168

Step-by-step explanation:

yea listen to the other person

Step-by-step explanation:

4x and 6y

im not sure though

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)
