## Emah Group Title 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... 2 years ago 2 years ago

$\frac{ x1 + x2 }{ 2 }, \frac{ y1 + y2 }{ 2 }$

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

ok thanks. the only thing that confuses me is the variables. but let me try it real fast ...

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
