Step-by-step explanation: x= 2-y then plug that in for x so y= 2-y+2;
y=4-y; -4y=-y; y=-1/4
Answer:
the interest rate is $183.89 =~ $ 184
Step-by-step explanation:
In this question, Antuan deposited $2590 into a 3 year CD (Certificate of Deposit) at an interest rate of 2.3% compounded quarterly. We need to find the interest account earned after 3 years.
Formula used will be :

Where
P= Principal amount
r= interest rate (in decimals)
n= no of times the interest is compounded
t = no of years
Here we are subtracting P because we only need interest amount and not the future value.
Using this formula and finding the value will be:
P= $2590
r = 2.3 % or 0.023
n = 4
t = 3


So the interest rate is $183.89 =~ $ 184
The formulas:

Plug the values into the expression:
Answer:
The only difference is that we line up the numbers according to the decimal point. For addition, it doesn't matter which number goes on the bottom.
