Question

Which values from the given replacement set make up the solution set of the inequality?

2b−4≥3 ; {2,3,4,5}

A. {2,3}

B. {3,4,5}

C. {4,5}

D. {2,3,4}

Answer 1

We can solve the inequality by adding 4 to both sides:

2b - 4 + 4 ≥ 3 + 4

2b ≥ 7

b ≥ 7/2

The values in the replacement set that are greater than or equal to 7/2 are {3, 4, 5}. Therefore, the solution set is:

{3, 4, 5}

So the answer is B. {3, 4, 5}.
