Which of the numbers 1, 2, and 3 is a solution of 2x+1≥7 ?(1 point)
Let's substitute each number (1, 2, 3) into the inequality and see which is a solution:
For x = 1:
2(1) + 1 ≥ 7
2 + 1 ≥ 7
3 ≥ 7 (False)
For x = 2:
2(2) + 1 ≥ 7
4 + 1 ≥ 7
5 ≥ 7 (False)
For x = 3:
2(3) + 1 ≥ 7
6 + 1 ≥ 7
7 ≥ 7 (True)
Therefore, the number 3 is a solution to the inequality 2x + 1 ≥ 7.
For x = 1:
2(1) + 1 ≥ 7
2 + 1 ≥ 7
3 ≥ 7 (False)
For x = 2:
2(2) + 1 ≥ 7
4 + 1 ≥ 7
5 ≥ 7 (False)
For x = 3:
2(3) + 1 ≥ 7
6 + 1 ≥ 7
7 ≥ 7 (True)
Therefore, the number 3 is a solution to the inequality 2x + 1 ≥ 7.
