Answer:

#-9-5i#

Explanation:

When you have a complex number in the form #a+bi#, its conjugate can be found by reversing the sign on the imaginary portion of the number, yielding the complex conjugate #a-bi#.

So, for the complex number #-9+5i#, the #+5i# is the imaginary part. In the complex conjugate, its sign will be #-# instead of #+#, so the complex conjugate of #-9+5i# is

#-9-5i#
