To calculate to volume of a rectangular prism you use the formula l × w × h = V
l, w, and h are the sides, and V is the volume
So... 24 × 10 × h = 2,880
h = 2,880 / 240
h = 12
If you equate both, the y is eliminated:
-6x-3 = -x+2
Simplify this to find x:
-5x = 5
x = -1
Fill in x=-1 in either equation:
y = --1 + 2 = 3
So (-1,3) is the solution, it is where the lines intercept.
f(X)=3/x-1,g(x)=2/x
g.f(-5)=g(f(-5))=g(-3/5-1)=g(-3-5/5)=g(-8/5)=2×(-5/8)=-5/4

If we find the unit rate for the graph, that means it's proportional. For the first question, we could see that the unit rate is 2/1, so it's proportional.
