Answer:
Explanation given below.
Step-by-step explanation:
The first step is to put the parabola in the form
, which is the <em>standard form of a parabola</em>
<em />
<u>Note:</u> a is the coefficient before x^2 term, b is the coefficient before x term, and c is the independent constant term
The axis of symmetry divides the parabola symmetrically. The axis of symmetry has the equation 
Where <em><u>a and b are the respective values shown above</u></em>
<em><u /></em>
So, that is how you get the axis of symmetry of any parabola.
The answer is 9 for this question

Answer:
Step-by-step explanation:
(x+30) + (x-23) + (2x-7) = 180 degrees
4x = 180
x = 45
m<1 = x+30 = 75 degrees
m<2 = x-23 = 22 degrees
Answer:
see below
Step-by-step explanation:
120-92= 28
28/4= 7
so 7 is the answer I guess
