2x + 3y = 12
I am going to put this in y = mx + b form, where m is ur slope and b is ur y intercept.
2x + 3y = 12
3y = -2x + 12
y = -2/3x + 4......slope is -2/3 and y int is (0,4)
x int can be found by subbing in 0 for y and solving for x
2x + 3y = 12
2x + 3(0) = 12
2x = 12
x = 6.....so x int is (6,0)
start at y int (0,4).....and since the slope is -2/3, come down 2 spaces, and to the right 3 spaces, then down 2 spaces, to the right 3 spaces....keep doing that and u should cross the x axis at (6,0)
Green is 50 and the blue is 30 degrees
- The annual rate of return of the investment that doubled in 15 years is 4.7%.
- The annual rate of return of the investment that doubled in 8 years is 9 years.
- The annual rate of return of the investment that doubled in 20 years is 3.52%.
- The number of years it would take the investment to double is 9.97 years.
<h3>What are the annual rate of return?</h3>
The formula that can be used to determine the annual rate of return is:
g = (Future value / present value)^(1 / number of years) - 1
2^(1/15) - 1 = 4.7%
(1600 / 800) ^(1/8) - 1 = 9%
(200,00 / 100,000)^(1/20) - 1 = 3.52%
Number of years = (In FV / PV) / r
Where:
- FV = future value
- PV = present value
- r = interest rate
IN2 / 0.0695 = 9.97 years
