= (x + 2)^2 - 4 - 11
= (x + 2)^2 - 15
B. vertex is at ( -2, -15) which is a minimum because the coefficient of x^2 is positive.
C. The axis of symmetry is a vertical line passing through the vertex It is
x = -2.
Answer:
50 =x
Step-by-step explanation:
The two angles are vertical angles, so they are equal
2 (x+10) = 3x-30
Distribute the 2
2x+20 = 3x-30
Subtract 2x from each side
2x-2x+20 = 3x-2x-30
20 = x-30
Add 30 to each side
20+30 = x-30+30
50 =x
