Answer:
i11, i26, i20, i21
Step-by-step explanation:
Alright, so there's an order to imaginary numbers. At the 1st power, it's i. At the second, it's -1. At the 3rd, it's -i. At the 4th, it's 1. And at the 5th, it restarts.

<h2>
Explanation:</h2>
In this exercise, we have the following functions:

And they are defined for all real numbers x. So we have to write the following expressions:
First expression:

That is, we subtract s(x) from r(x):

Second expression:

That is, we get the product of s(x) and r(x):

Third expression:
Here we need to evaluate:

First of all, we find the sum of functions r(x) and s(x):

Finally, substituting x = -2:

Answer:
10
Step-by-step explanation:
Step-by-step explanation:
y = 8x/9 - 2
therefore m = 8/9
x1 = -3
y1 = 6
from, y - y1 = m(x-x1)
y - 6 = 8/9(x+3)
y-6 = 8x/9 + 8/3
y - 8x/9 -26/3 = 0 (×9)
9y - 8x -78 = 0
