<u>Functions</u>
In a function, an independent variable, let's call it x is related to a dependent variable y and it can be expressed as:
y = f(x)
Let's consider the functions given in the question, where the equation that represents a company's yearly sales is:

And the equation that represents the same company's yearly expenses is:

The company's profit function P(x) can be found as the difference between S(x) and E(x), thus:

Operating:

Simplifying, the profit function for this company is:

Answer:
50 square feet
Step-by-step explanation:
Length x width
This means area of the park is in between the two numbers so we can write:
2.4 + 2.5 /2
= 2.45
Answer:
X=16
Step-by-step explanation:
10x-8=9x+8
First you have to simplify.
10x-9x=1x
So now the equation looks like this
x-8=8
Now you have to get x by itself
-8+8=0 and we have to do the same thing on both sides of the equal sign 8+8=16
The equation now looks like this x=16
And that's your answer
