This document discusses how to solve equations and inequalities involving absolute value. It introduces absolute value and notes that absolute value equations can be solved using the property that the absolute value of a number is equal to its distance from zero. It also states that absolute value inequalities can be solved using properties related to the fact that absolute value never results in a negative value.

?
The document discusses linear equations. It provides examples of equations and determines whether they are linear by rearranging them into the form of y = mx + b. It also shows how to graph linear equations by plotting the y-intercept and slope. Finally, it examines tables of ordered pairs and determines whether they represent linear equations based on whether the x and y values increase at a consistent rate.
Pres Absolute Value Inequalities (Section 1.8)schrockb
?
This document discusses rules and properties for solving absolute value equations and inequalities. It states that if a is greater than 0 and the absolute value of x is equal to a, then x equals a or negative a. If the absolute value of x is less than a, x is between negative a and a. If the absolute value of x is greater than a, x is less than negative a or greater than a. It provides examples of solving different types of absolute value equations and inequalities.
