The answers to the question are are the equations 
y = 0.08x²-1.6x+13 
y = 0.08(x-10)²+5
<h3>How to solve for the system of equations</h3>
David starts at (20, 13) and skates along a path that can be modeled by a quadratic function with a vertex at (10, 5).
Vertex form of quadratic function is
y = 
13 = a(x-10)²+5
let x = 20
a(20-10)²+5
13 = 100a + 5
take like terms
13 - 5 = 100a
8 = 100a
divide through by 100
a = 0.08
hence the equation would be 
y = 0.08(x-10)²+5

Answer:
80%
Step-by-step explanation:
Denise used 360 minutes out of 450 minutes. You would set this up as a fraction. Then, you would have to find out the percentage of how much Denise used. You would put 360/450 across from x/100. You find the value of x by multiplying 360*100 which equals 36000. You then would divide it by 450 to get a product of 80. This is how you would get 80%.
