Combining Like Terms
Simplify the expression
2a - 3b + 2a + 3b
4a + b
For which symbols do you use an open or closed dot on a graph showing an inequality?
Use an open dot for < > and a closed dot for
<= >=
Which term represents the product of a number and a power?
Exponent
4 + 3 x 2
11
Simplify the expression
12m + 2n - 7m + n
5m + 3n
For any inequality using the symbols shown below, which direction will the arrow on a graph travel?
> >=
To the right to show solutions that are greater.
How would you define an inverse operation? (give an example if needed)
The opposite operation, for example multiply/divide, add/subtract
5 x (6 - 2) ÷ 2
10
Simplify the expression
3x+2y-4x+5y
-x+7y
"y is greater than 5"
y >5
In the expression below, what does the "2" represent?
2x+5
Coefficient
12 ÷ (4 + 2)
3
Simplify the expression
4p + 3q + 2p - 5q
2p - 5q
How would you describe the possible solutions to the inequality
3y <= 9
Any number 3 or greater
Define the Associative Property of Addition and Multiplication.
The property states that regrouping addends (addition) or factors (multiplication) does not change the outcome of the sum or product.
8 - 2 x 3 + 4
10
Simplify the expression
3x + 2y - 4x - y + 5x
4x + y
What are the possible values of x for the inequality?
x+8>= 15
x >= 7
Define independent variables and dependent variables. Give an example if it helps you explain.
The dependent variable depends on the independent variable to change. The independent variable can change on it's own.
Example: feet per minute. Feet is dependent on minutes.
18 ÷ 2 + 4 x 3
