The correct response is A. 1, 2, 3, 4.
which of the numbers 1, 2, and 3 is a solution of 2x + 1 ≥ 7
To check which number is a solution for 2x + 1 ≥ 7:
1. For x = 1
2(1) + 1 = 2 + 1 = 3
3 ≥ 7 (It is false for x = 1)
2. For x = 2
2(2) + 1 = 4 + 1 = 5
5 ≥ 7 (It is false for x = 2)
3. For x = 3
2(3) + 1 = 6 + 1 = 7
7 ≥ 7 (It is true for x = 3)
Therefore, the number 3 is the only solution for the inequality 2x + 1 ≥ 7.
1. For x = 1
2(1) + 1 = 2 + 1 = 3
3 ≥ 7 (It is false for x = 1)
2. For x = 2
2(2) + 1 = 4 + 1 = 5
5 ≥ 7 (It is false for x = 2)
3. For x = 3
2(3) + 1 = 6 + 1 = 7
7 ≥ 7 (It is true for x = 3)
Therefore, the number 3 is the only solution for the inequality 2x + 1 ≥ 7.
