Asegment in the complex plane has a midpoint at 3 – 2i. if one endpoint of the segment is at 7 + i, what is the other endpoint?

Well, we know the midpoint is 3 - 2i.. well, skipping for a second the 'i', is just (3, - 2) then

one endpoint is at 7 + i, or 7 + 1i or , ( 7, 1)

let's say the other endpoint is at x,y



so, x = -1 and y = -5, that gives us ( -1, -5)   or   -1 - 5i on the imaginary grid

A) for the n row: 22+(n-1)×6therefore,b) 100-22=78that means (n-1)×6=7878÷6=1313+1=1414th row has 100 seats
