Don't worry, I'll help you!
1. What is a function?
"In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x2<span>."
</span>2. What is the difference between a linear and non-linear function?
"The equation of a linear function has no exponents higher than 1, and the graph of a linear function is a straight line. The equation of a nonlinear function has at least one exponent higher than 1, and the graph of a nonlinear function<span> is a curved line."
</span>
<span>3. Constant Interval, and how does it appear on a graph
</span>Definition:
"Determine the intervals on which a function is increasing, decreasing or constant<span> by looking at a graph. Determine if a function is even, odd, or neither by looking at a graph. Determine if a function is even, odd, or neither given an equation."
How does it appear on a graph?
</span>
"Functions can either be constant, increasing as x increases, or decreasing as x<span> increases."
</span>
<span>4. Identifying the rate of change
</span>
Yes, you can:
"Consider the line y = 2x + 1, shown at the right. Notice that this slope will be the same if the points (1,3) and (2, 5) are used for the calculations. For straight lines, therate of change<span> (slope) is constant (always the same). For every one unit that is moved on the x-axis, two units are moved on the y-axis."
</span>
<span>5. Determining if it is a linear function or not
</span>
"A linear function<span> is in the form y = mx + b or f(x) = mx + b, where m is the slope or rate of change and b is the y-intercept or where the graph of the line crosses the y axis. You will notice that this </span>function<span> is degree 1 meaning that the x variable has an exponent of 1."

A graph with a dotted line running through the points (-4, 0) and (0, 6) shaded above the origin.
Jaqleen unloads a truck in x hours and Marco takes 2x hours.
Working together (x*2x) / (x+2x) = 5 hours
2x^2 / 3x = 5 Multiplying both sides by 3x equals 2x^2 -15x = 0
x = 7.5 hours
So Jaqleen takes 7.5 hours and Marco takes 15 hours
Double-Check (7.5 * 15) / (7.5 + 15) = 112.5 / 22.5 equals
5 hours Correct!!
Answer:
432 liters
Step-by-step explanation:
Because the container was already 4/9 full, 240 liters is 5/9 of the whole.
1. Convert 5/9 to a decimal and then a percent by dividing the fraction and then multiplying by 100:
5/9 = 0.5556 = 55.56%
2. To determine what number 240 is 55.56% of, write the equation like this:
0.5556x = 240
(In which x = the number you are solving for)
3. Divide both sides of the equation by 0.5556 to isolate the variable.
x = 
x = 432 (Don't forget the unit, liters)
4. To check your work, make sure that 240 is 5/9 (55.56%) of 432:
432 × 0.5556 = 240
(Note: Because the fraction converts to a repeating decimal, I had to round it. This means the answer is a very small decimal off from the actual answer that I put.)
