solve each inequality and graph its solution a. 2x> -12 b. y + 5 _>2 c. x\4 _> -1 d.6z-3-5z<4

  • math - ,

    a. 2X> -12.

    X > -6.
    Graph: Open circle at -6 with arrow
    pointing rt. The open circle means that
    -6 is NOT a part of the solution.
    Always use the OPEN circle when there is no equal sign in your inequality.

    Solution Set:

    b. Y + 5 >= 2.
    Y >= 2 - 5,
    Y >= -3.
    Graph: Closed circle at -3 with arrow
    pointing rt. The closed circle means
    that -3 is a part of the solution.

    The Solution Set: Y = -3, and all values of Y > -3.

  • math - ,

    a. Solution Set: All values of X > -6.
