Answer: <em>time = 55.48 years</em>
Explanation:
Given:
Principal amount = $10000
Interest rate = 2% p.a
Amount = $30000
We can evaluate the time taken using the following formula:


Solving the above equation, we get

Now taking log on both sides, we get;

<em>time = 55.48 years</em>
Assuming you are asking
does -2x+y=6 and y-2x=4 have a solution
look at them
rewrite first equation by switching x and y
y-2x=6 and
y-2x=4
false since they are same values
there is no solution
these 2 lines are paralell
NO SOLUTION
The answer is 3 diagonals
To find
, you can switch the "x" and "f(x) or y" in the equation.
![y = \sqrt[3]{x-2}+ 8](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B3%5D%7Bx-2%7D%2B%208)
![x = \sqrt[3]{y-2}+8](https://tex.z-dn.net/?f=x%20%3D%20%5Csqrt%5B3%5D%7By-2%7D%2B8)
Now you need to isolate the "y"
Subtract 8 on both sides
Cube ( ³ ) each side to get rid of the ∛
![(x-8)^{3} = (\sqrt[3]{y-2}) ^{3}](https://tex.z-dn.net/?f=%28x-8%29%5E%7B3%7D%20%3D%20%28%5Csqrt%5B3%5D%7By-2%7D%29%20%5E%7B3%7D)
Add 2 on both sides
