Answer:
If I am wrong please forgive me I haven't messed with triangles in a while but I believe x is 39 degrees

Answer: x = -1</h3>
Explanation:
The given quadratic is in the form y = ax^2 + bx + c
We have a = 1, b = 2, c = 2
This then leads to
h = -b/(2a)
h = -2/(2*1)
h = -1
This is the x coordinate of the vertex (h,k)
The axis of symmetry is the vertical line passing through the vertex. So it must share the x value in question.
Meaning the axis of symmetry is x = -1. Every point on this vertical line has an x coordinate of -1. This line of symmetry splits the parabola into two equal mirrored halves.
I recommend using a graphing tool like Desmos to visually confirm the answer.
Y = 30 + .25x
the cost = $30 (constant - same every month) + 25 cents per minute
