It's a cube so x should also equal 6
For the first equation, I put it in y=mx+b form, so y=-3x-9
the second one is x=4
hope i helped
Is this what you’re looking for
y=-2/5x+3/5
I got -3.........................
-7 - 7p = 3p + 23
Move the -7p over to the right....by adding
-7 = 10p +23
Move the 23 over to the left by subtracting
-30 = 10p
divide by 10
p = -3
