Answer: 2880
Explanation: First, multiply 40 and 4 together to find the value of h. This should get you to 160. Then plug in 160 into h in the equation e=18h. This multiplies 18 and 160 together. You will then get an answer of 2880.
If I remember correctly, the solutions are only on the solid line or in the shaded area? therefore Answers could be:
6.) (-3,0.5) (-4,0) (-2,0) (-2,-5) (-3,-5) (-4,-1) (-3,-1) (-2,-1)
7.) (-1,0) (-2,0) (-3,0) (0,-1) (-4,-1)
