Answer:
The solutions of this system of equations are (-2, -2) and (1, 1).
Step-by-step explanation:
Let be the following system of equations:
(1)
(2)
(2) in (1):
This polynomial can be solved analytically by Quadratic Formula:
, 
Hence, the solutions of this system of equations are (-2, -2) and (1, 1).
$6.50 x 8 = $52 which is the hourly rate for her 8 hours
Then
$0.45 x 74 = 33.3
$33.3 + $52 = $85.30
If your asking to get dead on it's the closest I came because it would be under or over the $85
Use Pythagoras theorem:
a^2 = b^2 + c^2
-15^2 + 18^2 = a^2
a^2 = 99
a = root of 99
