Interchange (switch) the value of x and y in "y = x + 5" as x = y + 5, subtract 5 from both sides and re-write in the form "y = f(x)" as y = x - 5.
<h3>What is an inverse function?</h3>
In Mathematics, an inverse function can be defined as a type of function that is obtained by reversing (undoing) the operation of a given function (f(x)).
The steps required to write the inverse of f(x) = x + 5 include the following:
- Interchange (switch) the value of x and y in "y = x + 5" as x = y + 5.
- Subtract 5 from both sides, we have x - 5 = y.
- Re-write in the form "y = f(x)" as y = x - 5.

Assuming you have to solve it for f, you have to rewrite the equation in a form like f = ...
So in the form it is now, you're solving for C. You're not actually going to get values for f or C, for that you'd need more information.
So how do we convert the C = ... form into an f = ... form? Step by step you want to isolate f using simple rules:
step 1) I want to get rid of the 5 so we're dividing left and right by 5:
C/5 = 5(f-32)/(9*5) this simplifies to C/5 = (f-32)/9
step 2) Get rid of the 9 by multiplying by 9 left and right:
9*C/5 = 9*(f-32)/9 simplifies to f-32
step 3) I want to get rid of the -32 so I'm adding 32 left and right:
9*C/5 + 32 = f-32 + 32 simplifies to 9*C/5 + 32 = f
Now just swap left and right, and we get:
f = 9C/5 + 32
All you have to learn is the basic tricks like adding left and right, multiplying left and right. Hope this helps.
Answer:
3
Step-by-step explanation:
The least number of trees planted is the least common multiple (LCM) of 3 and 10. Because 3 and 10 have no factors in common, that value is their product, 3·10 = 30.
If group B plants 30 trees, they will have planted 3 clusters.
The answer for this question is
X=5
Answer: both
