Step-by-step explanation:
given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex which is also the axis of symmetry is
= -
y = 3x² - 24x + 38 is in standard form
with a = 3, b = - 24 and c = 38, hence
= - = 4
Substitute x = 4 into the equation for corresponding y- coordinate
y = 3(4)² - 24(4) + 38 = 48 - 96 + 38 = - 10
vertex = (4, - 10)
equation of axis of symmetry is x = 4
First, you get you equation, which is 54x-540=918. Then you solve your equation. First, add 540 to both sides, get 54x=1,458. Then divide both sides by 54, and get x=27
