1. Convert percent into decimal (it will help)
2. Convert Decimal to fraction
I believe the answer would be
f(x) = (x-3)^2 +5
<span> -x^2 + -14x = 49
-(x^2 +14) = 49
-[(x+7)^2 -49] = 49
</span>
X + y = 8
Replace y as y = y Insert x back into the original
x + x - 2 = 8 5 + y = 8
2x - 2 = 8 - 5 - 5
+ 2 + 2 y = 3
2x = 10 (5, 3)

2 2
x = 5
