We are told that r is either more than 0 or less than or equal to -8. This means we need to create an orcompound inequality. For the first inequality, we have the phrase more than, so we can identify that the inequality symbol should be >.
& a number $r$ is more than 0
& r > 0
For the second inequality, we have the phrase less than or equal to, so we can identify that the inequality symbol should be ≤.
& a number $r$ is less than or equal to -8
& r ≤ -8
Combining the two gives us the compound inequality.
r > 0 or r ≤ -8
