Question

Check whether the number is a solution of the equation or the inequality. \(s-7 \geq 12-s ; 9\)

Short answer

No, the number 9 is not a solution for the given inequality since the inequality \(2 \geq 3\) is not true.

Step-by-step solution

- Substitute the given number into the inequality

Replace the 's' variable by '9' in the inequality: \(9-7 \geq 12-9\)

- Perform the operations

When we perform the subtraction on both sides of inequality, we get: \(2 \geq 3\)

- Check the validity of the inequality

To determine if '9' is a solution for the inequality, we need to check if the statement \(2 \geq 3\) is valid or not.
