The height of a stack of DVD cases is in a proportional relationship to the number of cases in the stack. A stack of cases and its height are shown. Find the constant of proportionality. Then use the constant of proportionality to find the height of a stack of cases.

To the number of cases in the stack hope this helped

Step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
