We have the following expressions:
x = 3 + 8i
y = 7 - i
-x * y = (- 3 - 8i) * (7 - i) = -21 + 3i - 56i - 8 = -29 -53i
2x-3y = 2 (3 + 8i) - 3 (7 - i) = 6 + 16i - 21 + 3i = -15 + 19i
-5x + y = -5 (3 + 8i) + (7 - i) = -15 - 40i + 7 - i = -8 -41i
x * 2y = (3 + 8i) * (14 - 2i) = 42 - 6i + 112i + 16 = 58 + 106i
Answer:
-x * y = -29 -53i
2x-3y = -15 + 19i
-5x + y = -8 -41i
x * 2y = 58 + 106i
The answer is 2,500. You must multiply both of the equations and add them together. The answer will be 2500.
<span>3x + 3y = –9
3x – 3y = 21
-----------------add
6x = 12
x = 2
</span>3x + 3y = –9
3(2) + 3y = -9
6 + 3y = -9
3y = -15
y = -5
x = 2 and y = -5

Answer:
A
Step-by-step explanation:
The product is opposite of the integer
For example
2 * -1 = -2
