Charlidamelio is overrated
For this case we have the following function:
y = 1/4 (x + 2) ^ 2 - 7
We derive the equation:
y '= 1/2 (x + 2)
Equaling zero we have:
1/2 (x + 2) = 0
We clear the value of x:
x + 2 = 0
x = -2
Answer:
The equation of the axis of symmetry for the parabola is:
x = -2
You would write AB with a horizontal line segment over the letters A and B
So you would write this 
If you cannot draw that on your computer, then I would stick to saying "segment AB".
Answer:

Step-by-step explanation:

So
supplementary angles are adding up to 180
lets say they are x and y
x+y=180
x is 59 times y
x=59y
subsitute
59y+y=180
add
60y=180
divide 60
y=3
subsitute
x=59y
x=59(3)
x=177
angles are
3 and 177 degrees
