3x^2+7x
18x^2-12x
-12x^3-8x^2
6x^3-18x^2+6x
So hmm check the picture below
and since you already covered solving system of equations, surely you'll breeze right through B)
Answer:
y <= -2x + 1
Step-by-step explanation:
The one that is selected is correct.
check the picture below. You can pretty much just count the units from the grid.
