Use absolute value and inequality notations to describe the following situations. You may use "`|`" for absolute value sign; ` < = ` for `\leq` and ` > = ` for `\geq`. e.g. you may use "`|x| \ > = \ 5`" for "`|x|\geq5`".
The distance between `x` and `17` is no more than `12`

The distance between `x` and `- 17` is at least `21`

`x` is at least `17` units from `0`

`x` is at most `17` units from `0`
