If there were 30 Girls, 4 Girls played for each part.
The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.
Step-by-step explanation:
Given,
Start up fee to receive internet = $30
Per month charges = $13
Total amount = $134
Let,
x be the number of months.
y be the total cost.
y = 13x+30
Putting y=134

The equation 13x+30=134 can be used to find the number of months Kenneth can receive internet service.

Vertex aka max or min point is found by -b/2a in form
f(x)=ax^2+bx+c
f(x)=-1x^2+8x+20
vertex x value is -8/(2)(-1)=-8/-2=4
input back to find y value
f(4)=-(4^2)+8*4+20
f(4)=-16+32+20
f(4)=36
max (since the graph opens down) is (4,36)
axis of symmetry is the x coordinate
max is (4,36)
axis of symmetrry is x=4
