Answer:
-1
Step-by-step explanation:
We know that i^4 is equal to one so what you do is divide by 4 and the remainder is your simplified version
In this case the remainder is two which means taht i^82 = i^2 = -1
The answer would be -2 i had the same problem on my quiz and the correct answer was -2
The answer is A. The data is a sample, so you can determine every answer with the word 'population' in it to be wrong.
Answer:
82% of what number is 369
82% of 450 is 369
Reorder both sides
3y-6x=9
7-4y-3x=9
Multiply both sides
-6x-3y=9
6x+8y=-4
Dived both sides
11y= 5
Y=5/11
Substitute the value of Y
-3x-4(5/11)
Equals —> -14/11
Answer : (5/11 , -14/11)
