Answer:
y=7/2x−10
Step-by-step explanation:
Let's solve for y.
7x−2y=20
Step 1: Add -7x to both sides.
7x−2y+−7x=20+−7x
−2y=−7x+20
Step 2: Divide both sides by -2.
−2y/2=−7x+20/2
y=7/2x−10
Answer:
Step-by-step explanation:
It’s wrong because it isn’t one of the zeroes for the equation
f(x)=-16x^2+64x+80
Divide by -16
x^2-4x-5
(x-5)(x+1)
Set them up to zero
x-5=0. x+1=0
x=5. x=-1
5 and -1 are your possible zeroes
