Final answer:
Option b) {6.5, 7 1/2, 8, 9 2/3} is the set of x values that will always make the inequality x ≥ 6 true.
Step-by-step explanation:
To determine which set of x values will always make the inequality x ≥ 6 true, we need to find the set of numbers that are greater than or equal to 6. Looking at the given options, we can see that option b) {6.5, 7 1/2, 8, 9 2/3} contains only numbers that are greater than or equal to 6. Therefore, option b) is the correct answer.
