You have to solve two equations simultaneously. The equations are:
.40c + .75d =$190
c + d = 300.
Multiply this second equation by -0.4 on both sides leaving you -0.40c -0.40d = 120. Subtract this new equation from the first and solve for d.
0.40c + 0.75d = 190
- 0.40c - 0.40d = 120
-----------------------------
0.35d = 70
Solve for d. 70/0.35d d = 200. Plug this number back into the original equation and c = 100.
Answer:
h(-5) = 22
Step-by-step explanation:
Step 1: Define
h(x) = 2 - 4x
h(-5) = x = -5
Step 2: Substitute and Evaluate
h(-5) = 2 - 4(-5)
h(-5) = 2 + 20
h(-5) = 22
