Question

solve the inequality and graph the solution. 18 > 9d plot the endpoints. select an endpoint to change it from closed to open. select the middle of the segment, ray, or line to delete it.

Explanation:

Step1: Isolate the variable d

Divide both sides of the inequality $18>9d$ by 9. Since 9 is positive, the direction of the inequality sign remains the same.
$18\div9 > 9d\div9$
$2 > d$ or $d < 2$

Answer:

The solution of the inequality is $d < 2$. On the number - line, an open circle is placed at 2 (because 2 is not included in the solution set) and the line extends to the left towards negative infinity.
