    Use graphs to find the set. (-9,7) n [0,8] Is it (0,7) or [0,7)

    notice we don't include x=7 because x=7 wasn't included in the second curvy line I drew

    we know it wasn't included in the second curvy line because there is an open circle

    I think you were confused on how to combined fractions that have a variable in it ...

    \[\frac{x}{4}-\frac{x}{5}\] like both 4 and 5 go into 20

    and that is why I chose 20 to be the bottom but this changes the top

    I know how to. I was just following the example that told me not to do it that way

    so so it is clear to you you should get (5x-4x)/20 ?
