Answer:
<h2>no real solution</h2>
Step-by-step explanation:


The best approximation for the solution to this system of equations is (-2.2,-3)
Option C is correct.
Step-by-step explanation:
Solving the system of equations to get the exact value of x:

Let

Putting value of y from eq(1) into eq(2)



So, Value of x is -2.2
The best approximation for the solution to this system of equations is:
x=-2.2 and y = -3
(-2.2,-3)
Option C is correct.

Answer:
Step-by-step explanation:
(.45)(288)= $129.60
(.75)(72)= $54
$129.60 + 54 = $184.60 is Audrey's pay
2+2=4
a^2+b^2=c^2
15^2-4^2
=225-16
