Answer:
u=0
Step-by-step explanation:
The equation for the total amount charged is y = 60 + 45x
<h3>How to create the equation?</h3>
The given parameters are:
Rate = $60 per service
Installation = $45
Let y represents the total charges and x represents the number of services.
So, we have
y = Installation + Rate * x
This gives
y = 60 + 45 * x
y = 60 + 45x
See attachment for the graph of the function

Answer:
D There is an infinite number of solutions to the system of equations
Step-by-step explanation:
When you put the first equation in standard form by dividing it by 2, you get ...
x -2y = 4
When you put the second equation in standard form by dividing it by 8, you get ...
x -2y = 4
These are the same equation, so describe the same line. There are an infinite number of (x, y) pairs that will satisfy this equation.
There is an infinite number of solutions.
It WON'T cost the same amount because the tax that comes after Ms. G buys the 5 books would just be adding the 8% tax once while adding the 8% tax to each book would cause the payment of the 5 novels to be higher.
