Answer:
q = 3 + 1/2r
Step-by-step explanation:
10q - 5r = 30
We want to solve for q
Add 5r to each side
10q - 5r+5r = 30+5r
10q = 30+5r
Divide by 10
10q/10 = 30/10 +5r/10
q = 3 + 1/2r
Answer:

Solve for the x-max or h :\

plug it in to equation to get k:/

-8+16+3=11=k

solve for a by pluging (0,0)
then a= -11/4
