The future value of $1,000 invested at 8% compounded semiannually for five years is 
<u>Solution:</u>
----------- equation 1
A = future value
P= principal amount
i = interest rate
n = number of times money is compounded
P = 1000
i = 8 %
(Compounding period for semi annually = 2)
Dividing “i” by compounding period
Solving for future value using equation 1
Answer:

Answer:
When there are numbers like that next to the radical it means multiply. like this: 2<u>√9</u>. You would first figure out the square root. <u>Square root of 9</u> is 3. 2 times 3 is 6.
After you figure out those problems, you just need to put the number, x, and y in an equation with 2 unknowns.
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
Get rid of fractions:
Multiply the whole equation, i.e. all terms both sides of the equals sign, by the denominator or the lowest common multiple of all denominators if there are multiple fractions in the equation;
In this case, only one term is a fraction and therefore has a denominator (i.e. 7), so it is this number we multiply the equation by to get:
7(y) = 7(-³/₇.x) + 7(3)
7y = -3x + 21
3x + 7y = 21
