Rule; y=5x<br><br> Table:<br> x | y<br> 2<br> 4<br> 6
Dahasolnce [82]

x | y
-
2 | 10
4 | 20
6 | 30

just plug the x values (2,4,6) into x in the equation and you get your y! example would be y=5(2) so y=10

Answer:

- Point of intersection = (4, 360)

- The meaning of the intersection (4,360) means that when 4 hours of repair has passed for either service, the price of each service will be the same ($360).

- If it takes 3 hours to fix your car: Amy's Auto Repair will be the cheapest of the two services.

Step-by-step explanation:

Set both functions equal to each other:

100+65x = 40+80x

Subtract from both sides:

65x-80x = -15x

40-100 = -60

Set the two new numbers equal to each other:

-15x = -60

Solve this equation:

-60 / -15 = 4

This means the answer to the x intercept is 4.

...Now we need to find the y intercept...

To figure this out, you need to substitute the x-intercept (4) in for any x in the equation:

100+65(4) = 40+80(4)... simplify... 100+260 = 40+320

Now solve this:

100+260 = 360 --- and --- 40+320 = 360...

360 = 360...this means the y-intercept is 360.

So, the answer to question 1 is (4,360)

Why Amy's Auto Repair shop will be cheaper than Mike's Repair Shop after 3 hours of service:

3 hours of Mike's service: 100+65(3) = $295

VS

3 hours of Amy's service: 40+80(3) = $280 - CHEAPER

I hope this helps :)
