<u>Functions to model reality </u>
There are situations in real life where some variables depend on other(s) and that dependency can be determined as a practical rule or from a well-known theory. The expression who relates those variables are commonly called functions and they become a very useful tool to analyze, explain and predict the behavior of such events.
We know the monthly budget of a company is x dollars. $20,700 out of it is spent on salaries. After deducting salaries, the remaining budget is
One-fifth of it is spent on office supplies, so the required function is

Answer: C. x+9</h3>
===============================================
Explanation:
Think of two numbers that multiply to -36 and also add to 5. Put another way: think of two factors of -36 that add to 5.
Those two numbers are 9 and -4 since
9 times -4 = -36
9 plus -4 = 5
So we have x^2 + 5x - 36 factor into (x+9)(x-4)
x+9 is one factor
x-4 is the other factor

Alternatively, you can use a graphing tool to locate the x intercepts, and that will in turn lead to the factorization. Or you could use the quadratic formula to get the job done. Completing the square is yet another tool to use. So there are multiple approaches.
