Question

solve the inequality and graph the solution.
q - 1 ≥ 4
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 q

Add 1 to both sides of the inequality $q - 1\geq4$. So, $q-1 + 1\geq4 + 1$.

Step2: Simplify the inequality

We get $q\geq5$.

Answer:

The solution of the inequality is $q\geq5$. On the number - line, we plot a closed circle at 5 (because the inequality is $\geq$) and draw a ray to the right of 5.
