Simplify the complex number i^39 as much as possible.

-i

Step-by-step explanation:

i =

= - 1

Every will be equal to -1, when n is even.

Break apart into ()()

Since 38 is even, will be equal to -1

-1*() = -i

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
