If the solution set is all numbers less than 9, which inequality describes it?

Explanation:
When a solution set includes every number smaller than 9, the inequality describing it is x < 9. The "<" symbol means strictly less than, so 9 itself isn’t included, but every number to the left of 9 is. For example, 8 or -5 fit, while 9 does not and anything bigger than 9 does not either. The other options either include 9 or numbers greater than 9, which doesn’t match the set of numbers smaller than 9.
