you have to divide 5 divided by 3/10 to get your answer
The steps to finding the inverse is writting:
- y = x + 5
- x = y + 5 (applying a change of variables).
- y = x - 5 (isolating y).
<h3>How to write the inverse of the given function?</h3>
Here we have the function:
y = f(x) = x + 5
Basically, to find the inverse we need to isolate x. The first step is writing
y = x + 5
Now let's do a <em>"false change of variables"</em> of x by y, so we get:
x = y + 5
Now we need to isolate y again:
y = x - 5
This is the inverse of the function f(x), we have:

Answer:
a subset of integers
Step-by-step explanation:
You have to look at the definition of the variable and the meaning of the function value in order to determine suitable domain values.
Here, the variable is defined as a number of dimes. It must be a non-negative integer, a subset of the integers. (We cannot count fractional dimes or negative dimes.)
___
Since the variable represents "a handful of dimes", there must be an upper limit on its value. We expect that it will be something less than 1000 (20 rolls of dimes), but it might be slightly more.
Answer:
1) When r = 2, M = 20.
2) When M = 540, r = 6.
Step-by-step explanation:
M is a directly proportional to r cubed
This means that the equation for M has the following format:
In which a is a multiplier.
When r=4 M=160.
We use this to find a. So
So
1) work out the value of M when r=2
When r = 2, M = 20.
2) work out the value of r when M=540
When M = 540, r = 6.
