Answer:

y=-3.5x^2+9.5x-4

Step-by-step explanation:

y=a*x^2+b*x+c

4=0+0+c => c=-4

2=a+b-4 =>a+b=6

1=4a+2b-4 => 4a+2b=5

2a+b=2.5

a+b=6

a=-3.5

b=9.5

X/8 + 12 = 16 
start by subtracting twelve from both sides
x/8 + 12 = 16 
      - 12   -12
You're left with x/8 = 4
Multiply both sides by 8
8× x/8 = 4 ×8
Your answer is x = 32
If you need to simplify, the answer is 2.
