A
Because A dictates the actual equation correctly
Answer:
AB=5.83
Step-by-step explanation:
Distance Formula=

Plugging our values in, we get:

And if we solve it like this:

We end up with:

Which is about 5.83
CF = CD + DF (since D is simply a point on the line, and C to that point added onto F to that point is CF), so 4y-9+2y-7=14. Adding it up, we get 6y-16=14 and adding by 16 we get 30=6y. Dividing both sides by 6, we get y=5. Plugging that into DF, we get 10-7=DF=3
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
