Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -x - 4
f(4) is x = 4
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(4) = -4 - 4
- Subtract: f(4) = -8
Answer:
16
Step-by-step explanation:
DE is the vertical line x=1. It extends between y=2 and y=7, a distance of 5 units.
EF is the horizontal line y=7. It extends from x=1 to x=4, a distance of 3 units.
Then the perimeter of half the rectangle is 5+3 = 8 units.
The perimeter of the rectangle is 2·8 = 16 units.
Let c represent the number of cars that the salesman has left to sell.
68 + c ≤ 125
68-68 + c ≤ 125 -68
c≤57
The solution is c ≤ 57. The salesman has at most 57 cars left to sell
Answer:
68 + c ≤ 125; c ≤ 57 cars or less left to sell.
