Question

which of the number lines represents the solution to the given inequality? b + 20 ≥ 41

Explanation:

Answer:

First, solve the inequality \(b + 20\geq41\). Subtract 20 from both sides to get \(b\geq21\). This means the number - line should have a closed - circle at 21 (because of the \(\geq\) sign) and an arrow pointing to the right. Looking at the number - lines, the correct one is B.
B. The number line with a closed - circle at 21 and an arrow pointing to the right.
