Q. Which of the following is a solution to the inequality below?−5≥uChoices:(A) u=−3(B) u=−8(C) u=−2(D) u=−4
Understand the inequality: Understand the inequality.The inequality −5≥u means that u must be less than or equal to−5.
Test choice (A): Test choice (A) u=−3. Plug in u=−3 into the inequality −5≥u. −5≥−3 This is not true because −3 is greater than −5.
Test choice (B): Test choice (B) u=−8. Plug in u=−8 into the inequality −5≥u. −5≥−8 This is true because −8 is less than −5.
Test choice (C): Since we have found a true statement with choice (B), we do not need to test the other choices. However, for completeness, let's quickly check them.Test choice (C) u=−2.Plug in u=−2 into the inequality −5≥u.−5≥−2This is not true because −2 is greater than −5.
Test choice (D): Test choice (D) u=−4.Plug in u=−4 into the inequality −5≥u.−5≥−4This is not true because −4 is greater than −5.
