Could someone help me out with this question..? Which of the following is the conjugate of a complex number with −4 as the real part and 2 as the imaginary part? 2i − 4 2i + 4 −4 − 2i −4 + 2i

OpenStudy (anonymous):

the real part stays the same and the imaginary part changes sign

OpenStudy (anonymous):

i get feelings all the time but in math definitions and logic must corroborate the feelings

OpenStudy (anonymous):

you have to change the sign on the imaginary term to get the conjugate.

OpenStudy (anonymous):

now she hears me...

OpenStudy (anonymous):

not b, c. -4 is the real part. the sign on the imaginary part changes sign. so -4 + 2 i is the original and -4 - 2i is the conjugate.

you got it girl
