The computation of the equation shows that the answers will be:
12. 340 units
13. 2(270) + (2 × x) = 690
14. x = 5
<h3>How to compute the equations?</h3>
12. The first equation that's given will be:
(13.50 × x) - (3.65 × x) = 3349
13.50x - 3.65x = 3349
9.85x = 3349
x = 3349/9.85
x = 340
The number to break even is 340 units
13. The equation that can be used to find the perimeter will be:
2(270) + (2 × x) = 690
540 + 2x = 690
2x = 690 - 540
2x = 150
x = 150/2 = 75
14. x + x + 2 + 8 = 20
2x + 10 = 20
2x = 20 - 10
2x = 10
x = 10/2
x = 5

<h3>
<u>Explanation</u></h3>
- How to see if a shown graph is function or not?
If we want to check that a graph is function or not, we have a way to check by doing these steps.
- Draw a vertical line, make sure that a line has to pass through or intercept a graph.
- See if a line intercepts a graph more than once.
If a line intercepts a graph only one point, a graph is indeed a function. Otherwise, not a function but a relation instead. That includes if a line intercepts more than a point which doesn't make a graph a function.
From the graph, if we follow these steps, we will see that a line will only pass or intercept the graph only one point. Hence, the graph is indeed a function. The following graph that is shown is called "Parabola" for a < 0.
<h3>
<u>Answer</u></h3>
The graph is a function.
16 - x = 27
x = -11
16 - x = 27
16 = 27 + x
16 - 27 = x
-11 = x
