the problem is 0 < less then or equal to 2x-4<8 I got the answer which is
2< less then or equal to x <6 how do i write this on a graph

  • math - ,

    If 2 <= x < 6
    draw the number line
    place a dot at 2 and an open circle at 6
    shade the line between the dot and the circle.

  • math - ,

    for the 2 you would color in a circle at 2 because it is less than or equal.

    for the 6 you would put an open circle (not colored in)

    Connect the two points with a dark line. That is your solution.
    To check that you are correct... choose a value for x in that region and check it in the original inequality.

    In some courses, they don't use the colored and no-colored circle.

    they use ( ) or [ ]

    The ) is used for the open circle
    the ] is used for the colored in circle.
