To find this:
<span>x = -1.3333333333333... </span>
<span>Multiply by 10: </span>
<span>10x = -13.3333333333... </span>
<span>Subtract x = 1.3333333333333333....: </span>
<span>9x = 12. </span>
<span>Divide by 9: </span>
<span>x = 12/9 = 4/3.</span>
Step-by-step explanation:
I will do the first one as an example.
To find the inverse of y = f(x), simply switch x and y, then solve for y.
y = 3 + 2 ln x
x = 3 + 2 ln y
x − 3 = 2 ln y
(x − 3) / 2 = ln y
y = e^((x − 3) / 2)
So the inverse function is:
f⁻¹(x) = e^((x − 3) / 2)
The original function told us the amount of water as a function of time.
The inverse function tells us the time as a function of the amount of water.

Answer:
A: 8/31
B: 5/13
C: The events are dependent because one happening doesn't effect the other happening, sometimes it just happens that it rains and snows on the same day
Step-by-step explanation:
A - A is 8/31 because of the 31 days 8 of them snow (combined from snow and both)
B - There are 13 days that it rains and on 5 of those days it also snows
It really does not matter, I tend to solve for x first simply because it comes before y, but you do whatever is easier for you.
