1 What are 4 solutions for 𝑥 > 5?
2 What are 4 non-solutions for 𝑥 > 5?
3 What are 4 solutions for 𝑥 ≤ 15?
4 What are 4 non-solutions for 𝑥 ≤ 15?
5 What 4 numbers are in the solution set of 𝑥 > 5 and 𝑥 ≤ 15, making both of these inequalities true?
6 How would that be different from the solution set of 𝑥 > 5 or 𝑥 ≤ 15, making at least one of these inequalities true?
