Answer:
x=3 y=2
Step-by-step explanation:
y=2
2x+y=8
Substitute y=2 into the second equation
2x+2=8
Subtract 2 from each side
2x+2-2=8-2
2x=6
Divide each side by 2
2x/2 =6/2
x=3
x=3 y=2
Y=8/3x-10 is the answer in slope intercept form
Given:
Principal amount = $2000
Rate of interest = 3.5% compounded quarterly.
Time = 6 years
To find:
The amount after 6 years.
Solution:
The formula for amount after compound interest is:

Where, P is principal, r is rate of interest in decimal, n is the number of time interest compounded in an year and t is the number of years.
The interest is compounded quarterly, so
.
Substituting
, we get




Approximate the value to the nearest hundredth.

The amount after 6 years us $2465.10. Therefore, the correct option is A.
