Answer:
- 2 - 3i
Step-by-step explanation:
given a complex number a + bi
then the conjugate is a - bi
The real part a remains unchanged while the sign of the imaginary part is reversed.
the conjugate of - 2 + 3i is - 2 - 3i
1/-5, because when x increases by 1, y decreases by 5
The product of the greatest common divisor and the least common multiple of two numbers is always the product of the two numbers. So, you have

72⁰_______3π m
360⁰______15π m
C = 15π = 2π r
r = 7•5 m
