Assuming that this is a compounding interest rate, we use the future value formula which is expressed as: F = P ( 1 + i )^n where F is the future value, P is the present value, i is the interest rate and n is the compounding periods. We do as follows:
F = P ( 1 + i )^n
8000 = 4000 ( 1 + 0.0553)^n
n = 12.88 yrs or about 13 years
Therefore, option D is the answer.
Answer:
B
Step-by-step explanation:
Answer:
X = -19
Step-by-step explanation:
Add x to both sides to get rid of -x
-163 = 13x + 84
subtract 84 from both sides
-247 = 13x
divide by 13
x = -19
We can put in 6 - 2x for y:
2x + y = 6
2x +(6 - 2x) = 6
2x + 6 - 2x = 6
6 = 6
Since this statement is true:
x and y are all real numbers.
