Given segment AB with endpoints A(2x, 4y) and B(10, 22), what is the midpoint? A.(2x+5, 4y+11) B.(x+2 ½ , y+5 ½) C.(2x-10, 4y-11) D.(x+5, 2y+11) I know the midpoint formula, but it doesnt seem to work out right. Can someone explain it to me...

    \[\frac{ x1 + x2 }{ 2 }, \frac{ y1 + y2 }{ 2 }\]

    \[\frac{ 10 + 2x }{ 2 }, \frac{ 22 + 4y }{ 2 }\] now simplify those fractions

    you can look at it like \[\frac{ 10 + 2 }{ 2 }\] then just remember to add the x back in on the top

    no\[ \frac{ 10 + 2x }{ 2 } = \frac{ 10 }{ 2 } + \frac{ 2x }{ 2 }\] same with the other side

    10/2 = 5 2x/2 = x 5 + x is the left side, you do the right side
