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:
Step-by-step explanation:
(- 4 - 2)² + (- 4 - 1)² = AC²
(- 6)² + (- 5)² = AC²
36 + 25 = AC²
AC² = 61
AC = √61
AC ~ 7.81 unitário

Answer:
A= 5/7b +8
Step-by-step explanation:
The basic idea is that you can do anything you want (except divide by
zero) to either side of the equation, so long as you do the same thing
to the other side, too.
