Answer:
x = 30.8
Step-by-step explanation:
88 - 55 + 5x -7 = 180
33 + 5x -7 = 180
5x -7 = 180 - 33
5x - 7 = 147
5x = 147 +7
5x = 154
x = 154/5
x = 30.8

Prob because you were giving away free points or broke the rules.
So the equation of the red graph is already given to us: 
. I assume you meant the blue graph?
We can use the vertex form: 
, where 
is the vertex. (We can ignore 
because is 1 for this graph.) Remember that the vertex is the maximum or minimum of a parabola and the point that the line of symmetry passes through. For f(x) the vertex is (0,0).
The vertex for 
is at 
on the coordinate plane. (4 left, 2 down)
Plug into the vertex form:
The double negative becomes a positive, and then you're done:
