3. Since a polynomial contains more than one algebraic term — a phrase that contains numbers, variables, and operators — an example of a polynomial might look like this:

2x + y

2x + y

x^{2} + 4x^{2} - 1

x^{2} + 4x^{2} - 1

x^{2} - 3

x^{2} - 3

All of the above

All of the above

4. T/F: A polynomial is an expression that is divided by a variable.

11. Before you graph or illustrate a linear inequality on a line, the first step is to simplify the equation. For example, 3x < 6+11-2y can be simplified to read:

3x < 15y

3x < 15y

3x < 19y

3x < 19y

3x < 17 - 2y

3x < 17 - 2y

12. T/F: When graphing linear inequalities, you want the y variable on the right and everything else on the left.

13. T/F: A formula is a special type of equation that shows the relationship between different variables.

True

True

False

False

14. Formulas can be rearranged to solve for different variables. Let’s say we are working with the following equation: a = x + yt. What is the variable a considered?

The subject

The subject

The total

The total

The main figure

The main figure

15. How do we make the subject y in the equation: a = ty + x?

Divide both sides by x, then subtract t from both sides

Divide both sides by x, then subtract t from both sides

Divide both sides by t, then add x to both sides

Divide both sides by t, then add x to both sides

Subtract x from both sides, then divide both sides by t

Subtract x from both sides, then divide both sides by t

16. T/F: The abbreviation ‘PEMDAS’ is used to help you remember the order of operations.
