Answer:
3) (0, 0)
4) (-1, 2)
Step-by-step explanation:
I find a graphing calculator provides a quick solution to a system of linear equations.
3) The solution is (x, y) = (0, 0)
4) The solution is (x, y) = (-1, 2)
__
In each case, the y-term can be eliminated by multiplying the first equation by 3. For problem 3) the resulting equations must be added. For problem 4), the resulting equations must be subtracted.

Answer:
f(x) = 5x - 30
Yes it is a function
Step-by-step explanation:
Because when you input 0 you get -30 we know it starts at 0 or (0,-30). This gives us b in the equation y = mx + b.
We know that for every 4 cars washed it increases by 20. So 20/4 is 5. This tells us m = 5.
Plug it all in and you get y = 5x - 30 or f(x) = 5x - 30
