Q. Which of the following is a solution to the inequality below?−12≥fChoices:(A) f=−12(B) f=−1(C) f=−9(D) f=−5
Understand the inequality: Understand the inequality.The inequality −12≥f means that f must be a number that is less than or equal to−12.
Evaluate choices: Evaluate each choice to see if it satisfies the inequality.Start with choice (A) f=−12.Check if −12≥−12 is true.Since −12 is equal to −12, the inequality holds.
Check choice (A): Since we have found that choice (A) satisfies the inequality, we can check the other options to ensure there is no other solution that also satisfies the inequality.Check choice (B) f=−1.Check if −12≥−1 is true.Since −1 is greater than −12, this does not satisfy the inequality.
Check choice (B): Check choice (C) f=−9.Check if −12≥−9 is true.Since −9 is greater than −12, this does not satisfy the inequality.
Check choice (C): Check choice (D) f=−5. Check if −12≥−5 is true. Since −5 is greater than −12, this does not satisfy the inequality.
Check choice (D): Conclude which choice is a solution to the inequality.Since only choice (A) f=−12 satisfies the inequality −12≥f, it is the correct solution.
