LINR 2 | Lesson 1 | Try This! Absolute Value

Try This!

Give the values \(a\) and \(-a\), each is the same distance \(a\) from zero.  The distance from zero is the absolute value of the number.

In general:   \(| a | = a\), if \(a ≥ 0\)

\(|a| = -a\) if \(a < 0\), note that -a represents a positive number

Try this:

1.  If \(|x | = 5\), what value(s) for \(x\) make the statement true?

2.  If \(|x–3 | = 5\), what value(s) for \(x\) make the statement true?

3.  If \(|2x–3 | = 5\), what value(s) for \(x\) make the statement true?

4. If \(|x| = -5\), what value(s) for \(x\) make the statement true?
