Answer:
3x-y=12
3x-12=y
to find value of
8x/2y
8x/2(3x-12)
8x/6x-24
8x/6x-8x/24
4/3-x/3
4-x/3
Step-by-step explanation:
10-11= -1 You could also input this number on a calculator
1) Since we have the slope, and one point we can find that linear equation using this point-slope formula. Plugging them we have:

2) Note that we had to add 1 to both sides, to keep the "y "on the left.
3) Therefore, y=-9x+10 is the answer.
The graph would be a parabola which passes through the origin and opens upwards
The domain is all Real x.
The range is y >= 0
For this you can just use a calculator and divide 2587.5 by 1150.
You should get $2.25 for the unit price. Hope this helped ^-^
