Answer:
Step-by-step explanation: 15 minus 6.2 is 8.8 thats how much he needs to fill upp if it is 3.50 a gallon you would multiply to get 30.8 thats how much money he spent on gas
Ok y is your y value from any point on the graph m is your slope x is the x value of any point from the graph and b is your y intercept that is where the line cross in the y line that is the vertical line in the graph
the quotient =215.3 repeating. so, you would do the 646 ÷ 215.3
So we are given a system:

Substitute x = 2 we get the system:

Multiply the first equation by -5 and the second by 2 we get the system:

Adding the two equations we get :

We find the value of y by using any of the other equations like this:

Final solution:
Answer:
The range is (-3,∞)
Step-by-step explanation:
There is no specific range so it is infinite.
Hope I could help, if I was correct I hope you can consider marking me as brainliest! :D
