Q. Which of the following is a solution to the inequality below?−1≤uChoices:(A) u=−8(B) u=−1(C) u=−6(D) u=−4
Evaluate choice (A): Evaluate choice (A) u=−8.Plug in the value for u in −1≤u.−1≤uReplace u with −8.−1≤−8Check if the inequality holds.
Evaluate choice (B): Since −1 is not less than or equal to−8, choice (A) is not a solution to the inequality −1≤u.
Step 2: Evaluate choice (B) u=−1. Plug in the value for u in −1≤u. −1≤u Replace u with −1. −1≤−1 Check if the inequality holds.
Evaluate choice (C): Since −1 is equal to −1, choice (B) is a solution to the inequality −1≤u.Step 3: Evaluate choice (C) u=−6.Plug in the value for u in −1≤u.−1≤uReplace u with −6.−1≤−6Check if the inequality holds.
Evaluate choice (D): Since −1 is not less than or equal to −6, choice (C) is not a solution to the inequality −1≤u.
Step 4: Evaluate choice (D) u=−4. Plug in the value for u in −1≤u. −1≤u Replace u with −4. −1≤−4 Check if the inequality holds.
