Question

Which values from the given replacement set make up the solution set of the inequality? 2b–4≥2 ; {1,2,3,4}

1,2

3,4

1,2,3

2,3,4

Answer 1

Answer: 3,4

Explanation:

Plug in each number for "b" in the inequality

2(1) - 4 ≥ 2

2 - 4 ≥ 2

-2 ≥ 2

1 is not a solution because -2 is not greater than or equal to 2.

2(2) - 4 ≥ 2

4 - 4 ≥ 2

0 ≥ 2

2 is not a solution because 0 is not greater than or equal to 2.

2(3) - 4 ≥ 2

6 - 4 ≥ 2

2 ≥ 2

3 is a solution because 2 is equal to 2.

2(4) - 4 ≥ 2

8 - 4 ≥ 2

4 ≥ 2

4 is a solution because 4 is greater than 2.

{3, 4} is your answer
