Which number line models the solution set of the following problem? one less than twice a number is no less than five. what is the solution set?

Option 1.

The solution set is: {n|n is a real number, n≥3}

Step-by-step explanation:

1. You must read carefully the information given in the problem: "One less than twice a number" indicates that you must write a number multiplied by 2 and subtract 1 from this term, as following:

2. "is not less than five" indicates that the result must be equal or greater than 5. Then, you obtain the following expression:

3. Now, you can solve for . Then, you obtain:

4. Then, the solution set is: {n|n is a real number, n≥3}.

5. The correct plot on the number line must show a circle on 3 (You must fill in the circle if the sign is or) with a line from that circle to the right.

5. Therefore, the answer is the first option.
