Y = x + 1...so sub in x + 1 for y in the other equation
2(x + 1) - x = 6
2x + 2 - x = 6
x = 6 - 2
x = 4
y = x + 1
y = 4 +
y = 5
one solution at (4,5)
The volume is approximately 50.27 cubic yards.
4(2 - x) > -2x - 3(4x + 1)
8 - 4x > -2x - 12x - 3
-4x + 2x + 12x > -3 - 8
10x > -11
x > -11/10
x > -1.1
Therefore, x = 0 and x = 10 zre solutions to the inequality.
