The solutions to the system of equations are (-2,-6) and (4,6)
<h3>How to determine the system of equations?</h3>
We have:
-2x + y = -2

Next, we plot the graph of both functions.
From the attached graph, the equations intersect at (-2,-6) and (4,6)
Hence, the solutions to the system of equations are (-2,-6) and (4,6)

Answer:
The minimum number of bicycles that must be produced and sold to break even = 20
Explanation:
The profit generated by producing and selling n bicycles per week is given by the formula:

To get the minimum number of bicycles that must be produced and sold to break even, let P(n) = 0 (Since break even means no profit is made)

Solve the resulting quadratic equation above

This means that, to break even, either 60 or 20 bicycles must be produced and sold
The minimum number of bicycles that must be produced and sold to break even = 20
Answer:
18 minutes
Step-by-step explanation:
5 mins = 10 pages
10 mins = 20 pages
15 mins = 30 pages
20 mins = 40 pages
Just keep adding 5 to the minutes and 10 to the pages. then if you divide 10 by 5 (10÷5) you get 2.
2 is the amount of pages you read in 1 minute.
so 1 minute = 2 pages
Since you only need to read 36 pages, you know that it would at least take you 15 mintes to read 30.
then you start adding 1 minute until you get to 36 pages.
15 minutes = 30 pages
16 minutes = 32 pages
17 minutes = 34 pages
18 minutes = 36 pages
Therefore, it should take 18 minutes to read all 36 pages.
(A shorter way of doing this would be doing 10÷5=2, then just dividing 36 by 2 (36÷2) and you would get 18 which would be the minutes it would take you to read all 36 pages if you read at 2 pages per minute.)
The answer would be A.
Simply substitute the x and y values into the equation,

Infinity is a number that gets closer & closer to zero and the y-intercept is always 2.
