Identify the real and imaginary parts of the complex number -1/2+5i. Real Part: Imaginary Part:

OpenStudy (freckles):

is that -.5+5i?

OpenStudy (freckles):

\[\frac{-1}{2}+5i\]

OpenStudy (freckles):

a+bi is a complex number where a is the real part and b is the imaginary part

OpenStudy (pinkkjazzy3):

its negative one half +5i

OpenStudy (freckles):

so example -2+3i -2 is the real part 3 is the imaginary part another example .25-3i .25 is the real part -3 is the imagainry pary

OpenStudy (freckles):

by the way -1/2 and -.5

OpenStudy (freckles):

anyways what do you think is the real part and the imaginary part for your question?

OpenStudy (freckles):

-1/2 is -.5* trying to type around my cat

OpenStudy (pinkkjazzy3):

i think the negative one half is the real part

OpenStudy (pinkkjazzy3):

but im not sure

OpenStudy (freckles):

correct! :)

OpenStudy (pinkkjazzy3):

and the imaginary is 5?

OpenStudy (freckles):

absolutely right

OpenStudy (freckles):

a+bi a is the real part (because it isn't next to the imaginary unit i) b is the imaginary part (because it is next to the imaginary unit i)

OpenStudy (freckles):

-5.+5i -.5 is the real part (because it isn't next to i) 5 is the imaginary part (because it is next to i)

OpenStudy (pinkkjazzy3):

thank you :)
