Question

4 you must be 25 or older to book an airbnb apartment. 21 22 23 24 25 26 27 28 29 30

Explanation:

Step1: Understand the Inequality

The condition is "25 or older", which translates to the inequality \( x \geq 25 \), where \( x \) is the age.

Step2: Represent on Number Line

To represent \( x \geq 25 \) on the number line, we look for the point at 25. Since it's "or equal to", we use a closed (filled) circle at 25, and then draw an arrow to the right (towards larger numbers) to show all values greater than or equal to 25. Looking at the number line with marks at 21,22,23,24,25,26,27,28,29,30, the closed circle should be at 25 and the arrow to the right.

Answer:

The correct representation has a closed circle at 25 and an arrow pointing to the right (towards 26, 27, etc.).
