Answer:
see below
Step-by-step explanation:
z = 9 + 3i
This is in the form a+bi where a is the real part and b is the imaginary part
1.The real part is 9
2. The imaginary part is 3
The complex conjugate is a-bi
3. complex conjugate 9-3i
4. 3i - z = 3i - (9+3i) = 3i -9 - 3i = -9
5. z-9 = 9+3i - 9 = 3i
6. 9-z = 9- (9+3i) = 9-9-3i = -3i
