Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -7(x + 2)
f(3) is x = 3
<u>Step 2: Evaluate</u>
- Substitute: f(3) = -7(3 + 2)
- Add: f(3) = -7(5)
- Multiply: f(3) = -35
Answer:
Length is 138 ft, area is 412 ft
Step-by-step explanation:
The length is determined by the perimeter, so add both side of the perimeter together, and you have your length. Area is determined by perimeter + Length, to add both sides of perimeter and length and you get 412 ft.
Answer:

Step-by-step explanation:
Let's call x1: The rate per hour of the number one mechanic. X2: The rate per hour of mechanic number two. The first thing you should do is identify the system of equations that best describes the problem. In this case it is a system of 2 equations with two unknowns which when solved gives a total of x1 = 85 $ / h and x2 = 50 $ / h. Attached solution.
