Answer:
The two complex numbers that make the equation true are 1 + i and 3 + 2i
(1 + i) + (3 + 2i) = 4 + 3i
Step-by-step explanation:
(1 + i) + (3 + 2i)
Combine the real and imaginary parts in numbers 1 + i and 3 + 2i
1 + 3 + (1 + 2)i
Add 1 to 3. Add 1 to 2.
4 + 3i
The two complex numbers that make the equation true are 1 + i and 3 + 2i
Answer: the system of equations that represents this situation are
12x + 6y = 180
x = 2y
Step-by-step explanation:
Let x represent the number of hardcover books that were sold in a day.
Let y represent the number of paperback books that were sold in a day.
The discount bookstore sells hardcover books for $12 and paperback books for $6. The total sales that day were $180. It means that
12x + 6y = 180
The number of hardcover books sold that day was twice the number of paperback books. It means that
x = 2y
