Answer:
The correct answer is the last option.
Step-by-step explanation:
When you have a fraction with complex numbers, the first step to simplify is to multiply up and down the conjugate of the denominator, this will eliminate the complex part of the denominator, and in this way you can separate the expression in its real and complex part.
For the expression:
The denominator conjugate is 4 + 2i
When multiplied, the denominator is:
Answer:
$240
Step-by-step explanation:
I = prt
I = (2,400) (0.04) (2.5)
note: I changed 4% to a decimal and 30 months to 2.5 years
I = 96 (2.5)
I = 240 <-- The interest

The simple interest accumulated on a principal of $ 2,400.00 at a rate of 4% per year for 2.5 years (30 months) is $240.00.

* Last time I did interest was in 6th grade and I don't remember much. So I am very sorry if my answer is wrong *
1) find x
y=1/(x+3) -4
y+4=1/(x+3) -4+4
y+4=1/(x+3)
x+3 =1/(y+4)
x= 1/(y+4) - 3
2) change x on y , and y on x
x= 1/(y+4) - 3
y= 1/(x+4) - 3 This is an answer.
