Question

Which number line represents the solution of 1/2 b ≥ 4 ?

Answer 1

Answer D

Explanation:

Solve for b:

`(1)/(2)b \geq 4`

Divide both sides by a half

`b\geq 8`

We see that its a greater than or equal too sign, which means the number line has to be facing to the right with a closed circle. Therefore, D is our answer.
