Question

find two complex numbers whose sum is an imaginary number

Answer 1

if the sum is only imaginary and not complex, then the real part of one of the complex numbers needs to have the opposite sign from the real part of the other.

Like (6 + 5i) + (-6 + 3i) = (6 + (-6)) + (5i + 3i) = 8i

But it sounds like you could choose any complex numbers that fit this pattern. The point is that the real portions need to be the negatives of each other so that the real portions add to be zero, leaving only the imaginary part.

Answer 2

thank you

Answer 3

ive got another

Answer 4

glad to help... hope it makes more sense now :)

Answer 5

go for it...

Answer 6

yup. the points (-3,2) and (5,2) lie on the graph of a quadratic function. explain how these points can be used the equation for the axis of symmetry. then write the equation for the axis of symmetery

Answer 7

so, I guess what they are saying is that you could think of a vertical line in between those 2 points, such that the points are the same distance from that line... the line acts like a mirror (sort of), and that line is the axis of symmetry.

Strange wording for the question though

Answer 8

great

Answer 9

where is the vertical line that evenly splits those two points?
