Question

solve the inequality and graph the solution.
-20 ≤ 10b
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.
your answer:
change my answer

Explanation:

Step1: Solve the inequality

Given \(-20\leq10b\). Divide both sides by \(10\).
\(\frac{-20}{10}\leq\frac{10b}{10}\)

Step2: Simplify

\(- 2\leq b\) or \(b\geq - 2\)

Answer:

The solution of the inequality \(-20\leq10b\) is \(b\geq - 2\). On the number - line, we have a closed circle at \(-2\) (because the inequality includes equality, \(\leq\) when we rewrite it as \(b\geq - 2\)) and a ray extending to the right.
