Answer: x = 9/4, y = 7/6
║<span>2x + 3y = 8
</span>║<span>4x - 6y = 2
</span>║4x + 6y = 16
║4x - 6y = 2
Add both equations together:
8x = 18
x = 9/4
Sub x = 9/4 into 2x + 3y = 8
2(9/4) + 3y = 8
9/2 + 3y = 8
3y = 7/2
y = 7/6
Step-by-step explanation:
Complex roots or imaginary roots must come in conjugate pairs. If -4i is a root, that means 4i is also a root.
A possible polynomial is:
y = (x + 4i) (x − 4i)
y = x² − 16i²
y = x² + 16
Answer:
For part 6: 39
Step-by-step explanation:
You have your starting number and then it gets added to a product of two numbers. 8 + (2x2) = 12. 12 + (2x3) = 18. 18 + (3x3) = 27. 27 + (3x4) = 39. That is the most logical answer I was able to find.
