Answer:
You can solve this by substitution method
substitute the value of Y from 2nd equation in the first thet will give you the value of X and once your find the value of X you can substitute that value in any of the equation and get the answer
Answer:
Pretty sure it would be the last one.
Not sure if you want me to do the work. All I can say is that it would be<em> very long.</em>
Answer:
So x=4 and y=-5 would work.
Step-by-step explanation:
When you multiply complex conjugates, you get a real result.
Example:

I replace
with -1 since
.
is a real number (there is no imaginary part, no i).
So what is the conjugate of 4+5i?
4-5i
So x=4 and y=-5 would work.
A multiple of the complex conjugate would work as well.




This is still a real number; there is no imaginary part,no i.
6
To solve this problem, you need to divide the total number of students going on the field trips with the number of students in each group.
44/7
= 6 R 2
Since, I assume there can <em>only</em> be groups of 7, the answer is 6.
Answer:
$3743.43
Step-by-step explanation:
The amount is given by the formula ...
A = Pe^(rt)
where P is the principal, r is the annual rate compounded continuously, and t is the number of years. Filling in the values, we get ...
A = $1600·e^(0.0425·20) = $1600·e^0.85
≈ $1600·2.33964685 ≈ $3743.43
The amount in the account will be $3743.43.
