Solve this inequality.

|k|>2.5

  • Math - ,

    |k| > 2.5
    k > 2.5
    or
    k > -2.5

  • Math - ,

    hmm
    agree with k>2.5
    However when you multiply or divide an ineqality by a negative, change the arrow direction
    -k >2.5
    so
    k < -2.5 in other words to the left on number line

  • Math - ,

    oh hahaha yeah, damon is right. i was thinking like, -3.5 > -2.5 and it's not.

  • Math - ,

    thanks
