• Algebra problems separate terms with + and –
signs. The expression 5x – 4 – 3x + 7 has 4 terms:
5x, 4, 3x, and 7. Terms having the same variable
can be combined (added or subtracted) to simplify
the expression.

Graphing Inequalities (9.7) pg. 118-119
An inequality is a sentence that contains a < , > , ≤ ,
or ≥ sign. Look at the following graphs of
inequalities on a number line. Graphing inequality
shows all the numbers that make the inequality
true.
X > 2 is read “x is greater than 2” since it is > and not ≥.
X ≤ 3 is read “x is less then or equal to 3” since the
inequality is ≤. The endpoint is filled in. The graph uses a
closed circle because the number 3 is included in the graph.
Graphing Inequalities (9.7) pg. 118-119
There can be more than one inequality sign. These are
called compound inequalities. For example:
1 < x < 4 is read “1 is less than x and x is less than 4.”
1
4
X < 1 or x ≥ 4 is read “x is less than 1 or x is greater than or
equal to 4.”

Subtracting (9.8) pg. 120
Homework: Multiplication/Division Number
Puzzle/Bring Composition Book Due TOMORROW.
Solving Inequalities by Addition and
Subtraction(9.8) pg. 120
Solving inequalities is similar to solving equations.
Example 11: Solve and graph the solution set for x – 2 ≤ 5
Step 1: Add 2 to both sides of the inequality so the variable
will be by itself.
x–2 ≤ 5
Step 2: Graph the solution set for the inequality.

Homework: MAKE SURE YOU HAVE COMPOSITION BOOK
Solving Inequalities by Multiplication and
Division (9.9) pg. 121
Solving inequalities is similar to solving equations.
Example 12: Solve and graph the solution set for 4x ≤ 5
Step 1: Divide both sides of the inequality by 4.
4x ≤ 5
Step 2: Graph the solution
