Question

solve the inequality and graph the solution.
16 ≤ 2f
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 f

Divide both sides of the inequality $16\leq 2f$ by 2. So, $\frac{16}{2}\leq\frac{2f}{2}$.

Step2: Simplify the inequality

$8\leq f$, which can also be written as $f\geq 8$.

Answer:

The solution of the inequality is $f\geq 8$. On the number - line, there is a closed circle at 8 (since the inequality is $\geq$) and the line extends to the right towards positive infinity.
