Answer: 7 3/10
seven as a whole number, and .3 equals to 3/10 when converted
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
400 divided by 1 million can be given as:
400/1000000
finding gcf of 400 and 1000000
gcf of 400 and 1000000 is 400
dividing both numerator and denominator by 400 we get
1/2500
