use interval notation to express the solution set of the inequality |2x + 3|> or equal to 9

  • College algebra -

    |2x + 3| ≥ 9
    then
    2x+3 ≥ 9 OR -2x-3 ≥ 9
    2x ≥ 6 or -2 ≥ 12
    x ≥ 3 or x ≤ -6

    I will leave it up to you to put that in the interval notation. We used the above notation in my days.
