Answer:
Third Option
Step-by-step explanation:
We know that the function
is defined as
. Since the denominator is
then we know that
when 
We also know that the division by 0 is not defined. Therefore, the limit of
when "x" tends to
is infinite.
The function
is the inverse of
By definition, if we have a function f(x), its domain will be equal to the range of its inverse function
. If
, then 
This also happens for the function 
If when
then when 
Then, the answer is:

Answer:
6
Step-by-step explanation:
because i just know it lol
Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
7 miles:2.5 hours
10 miles:? hour
10×2.5÷7=25/7. As a result, It took him 25/7 hours or 3 4/7 hours to ride 10 miles. Hope it help!
