URGENT 20 POINTS <br> Select each graph that shows a function and its inverse.
Andre45 [30]

Answer: Graph first and fourth.

Step-by-step explanation:

If a function is reflected through line y=x,, we obtained an inverse function of that function.

In first graph,

The function is reflected through line y = x,

Hence, in this graph we obtained inverse functions.

In second graph,

The function is shifted horizontally,

This is why we did not get an inverse function.

In third graph,

The function is reflected through x-axis,

This is why we did not get the inverse of the function.

In fourth graph,

The function is reflected through line y = x,

Hence, in this graph we obtained inverse functions.

DeAngelo is training for a half marathon. Today he is running 13.25 miles. He jogs for the first half hour at a rate of 5.5 mile
klemol [59]
The first thing we must know is the following definition:
  d = v * t
  Where,
  d: distance
  v: speed
  t: time
  Therefore, the total distance traveled in this case is:
  (5.5) * (0.5) + (1.5) * p = 13.25
  Rewriting:
  2.75 + 1.5p = 13.25
   Clearing the value of p we have:
  p = (13.25-2.75) / (1.5)
  p = 7
   Answer:
  an equation representing this situation is: 
  2.75 + 1.5p = 13.25 
  DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour
