Final answer:
The values that make the inequality u≥-7 true are any real number greater than or equal to -7. Any number right of -7 on a number line, including -7 itself, satisfies the inequality.
Step-by-step explanation:
The question asks for values that make the inequality u ≥ -7 (u is greater than or equal to minus seven) true. To solve this inequality, one should recognize that any real number that is greater than or equal to -7 satisfies the inequality. This is because when comparing numbers on a number line, any number to the right of -7, including -7 itself, is greater than or equal to -7.
So, for example, -6, 0, 5, 10, and 100 are all numbers that would make the inequality u ≥ -7 true. There is no upper limit to the values that can satisfy this inequality; hence the solution set is u ≥ -7, meaning u can be any real number greater than or equal to -7.
Remember that when dealing with inequalities, you can use an inequality symbol to show how two metric measurements are related, such as u ≥ -7 in this example.
