Which pair of expressions represents inverse functions? a. 4x+2/x-3 and 5x+3/4x-2 b. x+3/4x-2 and 2x+3/4x-1 c. 4-3x/4x-2 and x+2/x-2 d. 2x+5 and 2+5x

b

Step-by-step explanation:

Which pair of expressions represents inverse functions?

A.  

and  

B.  

and  

C.  

and  

D.  

and

In this question , we have to find, which option represents inverse functions.

Let's check out option b

Let it be y

So we have

Switching x and y and solving for y,

Performing cross multiplication

Combining like terms

Which is same as of the other function.

So correct option is b .

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
