Answer:
They are inverse functions
Step-by-step explanation:
A property of inverse functions is that if 
We can plug in x = 3

That means that, supposing they are inverse functions, g(7) should equal 3

It checks out
Another way to see if two functions are inverse is to swap the x and y of one of the functions.
ex. 
Since, after the swap, the functions are equal, we know it is an inverse function
So r+c=42
c=4+r
subsitute c=4+r for r in r+c=42
r+4+r=42
add like terms
2r+4=42
subtract 4 from both sides
2r=38
divide both sides by 2
r=19
rob=19
subsitute r=19 for r in c=4+r
c=19+4
carly=23
Answer:
3 4/5
Step-by-step explanation:
19/5 there are 3 wholes of 5.
5,10,15
3 wholes later we are left with 4
You just write it as 4/5. Meaning, the 4 is just left.
