OpenStudy (kirbykirby):

|x| > 5 then x > 5 and x < -5

OpenStudy (kirbykirby):

this comes from the definition of the absolute value: \[ |x|=\begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0 \end{cases}\] Thus, \(|x|>5\) means: \(x > 5, \text{if } x \ge 0\) \(-x > 5, \text{if }x<0\) so since you have a negative sign in the 2nd case, you flip the inequality when you divide both sides by a negative: \(x > 5 \) \(x < -5\)
