Answer:
![\sqrt{2}+9i](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D%2B9i)
Step-by-step explanation:
To make the conjugate of a complex number, <em>change the sign of the imaginary part</em>. The imaginary part is the part that has <em>i</em> as a factor.
Your number has real part √2 and imaginary part -9i. Changing the sign of the imaginary part makes it be +9i, so the complex number becomes ...

Answer:
x = -9
Step-by-step explanation:
6 - 2/9x = 8
Subtract 6 from each side
6-6 - 2/9x = 8-6
-2/9 x = 2
Multiply each side by -9/2 to isolate x
-9/2 * -2/9x = 2*-9/2
x = -9
