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.
