5x/7 + 5 = 30 solve for x? i can't figure it out.. \:
mixer [17]
First subtract 5 from both sides:
5x/7 = 25
Now multiply both sides with 7:
5x = 175
Divide by 5:
x = 35

What is the answer to this? i can’t figure it out.

Answer:

  25 +0i

Step-by-step explanation:

The conjugate of a complex number is that number with the sign of the imaginary part reversed.

For z = -3+4i, its conjugate z* is -3-4i. The product of z and z* is ...

  (-3 +4i)(-3 -4i) = -3(-3 -4i) +4i(-3 -4i)

  = 9 +12i -12i -16i² = 9 +16 = 25

The real part of the product is 25; the imaginary part is 0.

  (-3 +4i)(-3 -4i) = 25 +0i

_____

You may have noticed that (z)(z*) = |z|², the sum of the squares of the real and imaginary parts. It is always a non-negative real number.
