I will summarize how to solve absolute value inequalities algebraically.

Lesson 11 Solving Absolute Value Inequalities

Multiple Choice

Formulate the absolute value equation from the problem in the picture.

|x - 6.4| = 58.2

|x - 400| = 6.4

|x - 58.2| = 6.4

|x - 400| = 58.2

Inequalities will be solved very similarly to equations. Graphing will look a little different and there will be some special cases we will look at.

Remember the definition of absolute value**

If we use the symbol ≥ or ≤ we will have a CLOSED circle on the graph

For symbols > or < the circle will be open for only that value.

Key Idea:

Dropdown

If you see this symbol, ≥, we will

the circle on the graph.

Dropdown

If you see this symbol <, we will

the circle on the graph.

equation

If you see these cases, know how the definition of absolute value works to save time!!

Don't waste time on these Special cases

Dropdown

Don't waste time working out a problem like this:

\left|x-2\right|

0

, because it is

true.

Dropdown

Don't waste time working out a problem like this:

\left|x-2\right|

-2

, because it is always true.
