Answer:
it is classified as a drug for these reasons
Explanation:
Considering the definition and sum of complex numbers, the sum (9 + 4i) + (–1 - 7i) gives as a result 8 -3i.
Complex numbers are combinations of real numbers and imaginary numbers.
In other words, complex numbers are numbers that have a real part and an imaginary part.
The most common representation of a complex number is the sum of a real part and an imaginary part. At the same time, the imaginary part is divided between the imaginary part and the imaginary unit:
z = a + bi
where
This expression is called the binomial form of the complex number z.
To add two or more complex numbers, you simply have to add the real and imaginary parts separately. That is, being z1 = a + bi and z2 = c + di, the sum of both complex numbers is calculated as:
z1 + z2 = (a + c) + (b + d) i
In this case, to obtain 8 -3i you have to sum:
(9 + 4i) + (–1 – 7i)= (9-1) + (4-7)i= 8 - 3i
So, the sum (9 + 4i) + (–1 - 7i) gives as a result 8 -3i.

Carlos is a senior and is looking forward to taking his girlfriend, Rachel, to the prom this
spring, but he needs to save his money to rent a tux. Carlos works part-time and brings
home $150 each week. He bought a used car last month and his payment is $200 per
month. His parents cover his insurance, but he must cover his gas ($15 a week) to and
from work and school. Carlos also has a cellphone, which costs $85 per month. He
hopes to attend college this fall and plans to live at home, but he needs to save up to
pay for his tuition and books. In order to afford the fall semester, he needs to
contribute $200 each month to his college savings account. Looking at his budget, how
much does Carlos have left over each month to put towards his tux rental?
O $75
O $55
$25
O $100
The correct answer is B. $55
Explanation:
To solve this mathematical problem you need to find the total budget of Carlos and then deduct all his monthly expenses, which would be equivalent to the money left for his tux.
1. To begin, we know each week Carlos earns $150, this means the total each month is $600 ($150 x 4 weeks each month = $600)
2. The expenses of Carlos include $200 for his car each month, $15 of gas each week or $60 each month ($15 x 4 = 60), $85 for his cell phone each month, and $200 for his tuition. This means, his total expenses are $545 ($200 + $60 + $85 + $200 = $545)
3. This means the money left for his tux is $55 as $600 (total of money) - $545 (total of expenses) = $55 (money left)
The Easiest way to solve this problem is to add the numbers absolute values. The answer is 14,776. The difference is 14,494 - (-282) = ? Two -'s = a + so its 14,494 + 282 = 14,776 :D
