Question

a person must bea) which three of these ages can a person be to set up an account?13 14 19b) let $x$ be an age, in years.$x \geq 13$c) graph the inequality $x \geq 13$.d) does the graph of $x \geq 13$ have an open circle or a closed circle at 13?closed

Explanation:

Step1: Identify valid ages

From $x \geq 13$, ages $\geq13$ are valid.
Valid ages: 13, 14, 19

Step2: Determine circle type

For $\geq$ or $\leq$, use a closed circle.

Step3: Graph the inequality

Mark closed circle at 13, shade right.

Answer:

1. Valid ages: 13, 14, 19
2. Circle type: closed
3. Graph: Draw a closed circle at 13 on the number line, then shade all values to the right of 13.
