Step-by-step explanation:
step 1. the standard form of a quadratic equation is f(x) = ax^2 + bx + c
step 2. since they are all in standard form you need to provide more information.
Answer:
23
if y=8 then you plug it inti the equation
2(8)+7
16+7=23
x = 24
y= -16
-16 x 6 = -96
y= -96
x= 4
4 x 6 = 24
x=24
5²=4²+x²
25=16+x²
25-16=x²
9=x²
√9=√x²
3=x
