Question

6 ximena studied no less than 20 minutes for her math test.

Explanation:

Step1: Interpret the Phrase

"no less than 20 minutes" means the time \( t \) satisfies \( t \geq 20 \).

Step2: Represent on Number Line

To graph \( t \geq 20 \) on the number line, we use a closed circle at 20 (since 20 is included) and an arrow pointing to the right (for values greater than or equal to 20). The given number line has 20 as a mark, so we place a closed dot at 20 and draw an arrow to the right.

Answer:

The graph should have a closed circle at 20 and an arrow pointing to the right (towards values greater than 20) on the number line.
