Answer:
x = 3
Step-by-step explanation:
given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the equation of the axis of symmetry is
x = - 
y = x² - 6x +
is in standard form
with a = 1 and b = - 6, hence
x = -
= 3
equation of axis of symmetry is x = 3
Multiply the integrand's numerator and denominator by
, then simplify:

You should be familiar with


so that

Answer:
A. 6.75
Step-by-step explanation:
8x+18=4x+57
8x-4x=57-18
4x=39
4x+57=180-(8y+30)
39+57=180-8y-30
96=150-8y
8y=150-96
= 54
y= 54/8 = 6.75
