    3 positive integers

    Step-by-step explanation:

    -2x + 1 ≥ - 6

    -2x≥-6-1

    -2x≥-7

    2x≥7

    Divide both sides by 2

    2x/2≥7/2

    x≥7/2

    x≥3.5

    By interpretation, it reads x greater than or equal to 3.5

    That's 1, 2, 3 and even 3.5

    That's 3 positive integers
