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.(2x10, 4y11)
D.(x+5, 2y+11)
I know the midpoint formula, but it doesnt seem to work out right. Can someone explain it to me...

\[\frac{ 10 + 2x }{ 2 }, \frac{ 22 + 4y }{ 2 }\] 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
