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:

Explanation:

Step1: Solve the inequality

Divide both sides of the inequality \(-20\leq10b\) by \(10\).
$$\frac{-20}{10}\leq\frac{10b}{10}$$

Step2: Simplify

Simplify the left - hand side \(\frac{-20}{10}=-2\) and the right - hand side \(\frac{10b}{10}=b\).
So, \(b\geq - 2\)

Answer:

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