To find the solution to the inequality, we need to isolate x on one side of the inequality sign. First, we add 9 to both sides of the inequality to get:
4x - 9 + 9 ≥ -21 + 9
This simplifies to:
4x ≥ -12
Next, we divide both sides of the inequality by 4 to solve for x:
4x/4 ≥ -12/4
This simplifies to:
x ≥ -3
So, the solution to the inequality is x ≥ -3.
On a number line, this would be represented by a closed circle on -3 and a line extending to the right.
The number line that represents the solution of the inequality 4x - 9 ≥ -21 is:
