Answer with Step-by-step explanation:
We are given that a function

a.We have to find the inverse of m.
Suppose, 




Replace x by y and y by x

Substitute 

b.When the inverse function of given function is 
Then , we get fog(x)=

When f and g are inverse to each other then fog(x)=Identity function.
c.If f(x)=x
It is self inverse function.
Answer:

Step-by-step explanation:
The volume of a cone is given as:

where r = radius
h = height of cone
The height of the cone is 17.7 cm and its base radius is 7.9 cm (diameter is 15.8 cm).
Its volume is:

Hello!
To find this ordered pair, we solve for x and y and put them together in an ordered pair.
-4+y=8
x-5y=17
Let's solve the first equation for y.
y= 12
Now, let's plug 12 into the second equation for y.
x-5(12)=17
x-60=17
x=77
Therefore, our ordered pair is (77,12)
I hope this helps!
