If z = a-bi, the complex conjugate of z is a + bi.
So the imaginary part is "b"
"b" is opposite of -b, so correct answer is c)
A is proportional.
Lets simplify the problem,
← divide numerator/ denominator by 4
= 4/20= 1/5
Thus A form a proportion
≠ 1/5
Thus B is not a proportion
← divide numerator/ denominator by 4
= 2/5 ≠ 1/5
Thus C is not a proportion
5/1 ≠ 1/5
Thus D is not a proportion
A is proportional.

Answer:
30
Step-by-step explanation:
Each exterior angle is 180 -168 = 12 degrees. The sum of them is 360, so there are ...
360/12 = 30
exterior angles, hence 30 sides to the polygon.
Answer:
D. y + 7 = -3(x - 5)
Step-by-step explanation:
Point-slope form: y - y₁ = m(x - x₁)
⇒ y - (-7) = -3(x - 5)
⇒ y + 7 = -3(x - 5)
