You would also need to know the opposite segment of the given angle because sine is equal to opposite over hypotenuse.
To get X and Y by itself, move everything else to the other side of the equal sign. Do this by doing the opposite operation.
Example: x-2y=11
add 2y to both sides to get x by itself
x=2y+11
Let the constant be k.
For an inverse squared proportion the formula is y = k/x^2
Insert values of y and x into the formula.
3 = k/(-4)^2
3(-4)^2 = k
k = 3(16)
k = 48
Hope this helps. :)
Answer:
Zero solution.........
STEPS:
6(x-1)=6x-1
6x-6=6x-1
6=1.....

CHECK YOUR CALC FIRST.....
First we want to find the amount that will be worth 20.7 after one year and 23.81 after two years
So I assume that
Y =p (1.15)^x
Where
Y 20.7
P ?
X 1 year
20.7=p (1.15)^1
Solve for p
P=20.7÷1.15
P=18
The answer is
Y=18 (1.15)^x
