Y=4x+7
So 4 is the rate of change because if you solve for y, x is the rate of change
Answer:
Step-by-step explanation:
m (x) = (x+ 5) / (x -1) and n(x) = x - 3.

Hence

but n is a function and n = x-3. Now, replace value of n on m (n)

simplify it

since (m . n) (x) is a fraction function, its domain will be all x such that the denominator is NOT 0. That is

among options, only C has the same denominator with 
Hence their domains are the same.
Answer:
first off here are the things you need to know:
She parked her car 4 levels below the street
so let's make that 4
and he doctor's office is at the fifth level of the building which makes it 5
