Preston solved an inequality and graphed the solution on the number line. Which of the following inequalities did he solve? Number line from 10 to -10. Closed circle on 1.5 going to 10
The inequality that Preston solved is:
$1.5 \leq x \leq 10$
This inequality is represented by the closed circle at 1.5 and the line segment extending to 10 on the number line.
