Elevator 1 in a building moved from ground position to a final position of +13 feet. Elevator 2 in the same building moved from
Marina CMI [18]

The correct answer I believe you are looking for is D. Elevator 1 is 13 feet above ground level, and Elevator 2 is 10 feet below ground level.

<u>Explaination:</u>

This is because if you start at (0, 0) Elevator one, will go up 13 on the y axis. Putting it at 13 feet above ground level. If you start Elevator 2 at ground level on (0, 0) and go down 10 it will make it -10 AKA 10 feet below ground level.


I hope this helps! :)

What is the value of x?
blsea [12.9K]
Since these are supplementary angles  (two angles which sum to 180°) we can say:

4x+x=180  combine like terms on left side

5x=180  divide both sides by 5

x=36°

What is the answer for P=, cost, and labor?
ollegr [7]

9514 1404 393

Answer:

  • P = 160x +220y
  • cost: 50x +70y ≤ 7400
  • labor: 20x +25y ≤ 3500

Step-by-step explanation:

As with all cost problems, the total cost is the sum of products of number of items and item unit cost. Here, the items are acres of crops, and their unit costs are the respective cost per acre.

  cost: 50x +70y ≤ 7400

Labor hours are added in similar fashion. The unit costs for labor hours are hours per acre for the different crops

  labor: 20x +25y ≤ 3500

The profit function follows the same pattern:

  P = 160x +220y
