If \(7x\geq -21\), what is the correct solution?
Explanation opens after your attempt
A. \(x\geq -3\)
Concept
Dividing by positive (7) does not change the direction of the inequality. Therefore \(x\geq -3\).
Why this answer is correct
The correct answer is A. \(x\geq -3\). Dividing by positive (7) does not change the direction of the inequality. Therefore \(x\geq -3\).
