Q. Which of the following is a solution to the inequality below?\newline5u-5 \geq u\newlineChoices:\newline(A) u=3u = -3\newline(B) u=8u = -8\newline(C) u=2u = -2\newline(D) u=4u = -4
  1. Understand the inequality: Understand the inequality.\newlineThe inequality 5u-5 \geq u means that uu must be less than or equal to 5-5.
  2. Test choice (A): Test choice (A) u=3u = -3. Plug in u=3u = -3 into the inequality 5u-5 \geq u. 53-5 \geq -3 This is not true because 3-3 is greater than 5-5.
  3. Test choice (B): Test choice (B) u=8u = -8. Plug in u=8u = -8 into the inequality 5u-5 \geq u. 58-5 \geq -8 This is true because 8-8 is less than 5-5.
  4. 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.\newlineTest choice (C) u=2u = -2.\newlinePlug in u=2u = -2 into the inequality 5u-5 \geq u.\newline52-5 \geq -2\newlineThis is not true because 2-2 is greater than 5-5.
  5. Test choice (D): Test choice (D) u=4u = -4.\newlinePlug in u=4u = -4 into the inequality 5u-5 \geq u.\newline54-5 \geq -4\newlineThis is not true because 4-4 is greater than 5-5.
