4) You decided whether a number is a solution of an inequality. Which of these numbers is a solution of the inequality \( 3 x \geq 18 \) ?

To determine which numbers are solutions to the inequality \( 3x \geq 18 \), we will first solve the inequality for \( x \). ### Step 1: Solve the inequality We start with the inequality: \[ 3x \geq 18 \] To isolate \( x \), we divide both sides of the inequality by 3: \[ x \geq \frac{18}{3} \] ### Step 2: Simplify the right side Calculating the right side gives: \[ x \geq 6 \] ### Conclusion The solution to the inequality \( 3x \geq 18 \) is \( x \geq 6 \). ### Step 3: Identify solutions Any number that is greater than or equal to 6 is a solution to the inequality. For example, numbers like 6, 7, 8, etc., are solutions, while numbers like 5, 4, 3, etc., are not. If you have specific numbers to check, please provide them, and I can confirm whether they are solutions to the inequality.
