Question

solve the linear inequality for b and graph the answer in the number line. then write the solution in inequality notation.
3 ≤ b + 4
isolate b by removing +4 from the right side

Explanation:

Step1: Isolate the variable b

Subtract 4 from both sides of the inequality $3\leq b + 4$. So, $3-4\leq b+4 - 4$.
$3 - 4=-1$ and $b+4 - 4 = b$, resulting in $-1\leq b$.

Answer:

The solution in inequality notation is $b\geq - 1$. On the number - line, you would have a closed circle at - 1 (because the inequality is $\geq$) and an arrow pointing to the right.
