Answer is the 2nd one.
Step-by-step explanation:
Answer:
X=1
Step-by-step explanation:
Solve for the vertex of the parabola: (v)
The axis of symmetry for a parabola will always be x=v.
Graphing the function shows the vertex at (1,-9) so the line denoting the axis of symmetry will be x=1.
Answer:
40
Step-by-step explanation:
angle CHA is equal to angle HGB because they are alternate interior angles.
This means that angles CHA and AGH are supplementary, add up to 180 degrees.
So, 5x + x + 12 =180
6x = 168
x = 28
<CHG = x + 12 = 28 + 12 = 40
