Answer: 6a 2(a+2a) and the last one
Step-by-step explanation:
First, conceptually understand what an inverse function is, it makes solving it very intuitive. An inverse function is simply a function which has points (y,x) for every point (x,y) of the parent function. So you are essentially taking all points of the parent function and switching the x and y coordinates for each. Those switched coordinates are produced by the "inverse function".
Mathematically then, finding the inverse function is a matter of solving for x and then switching the variable labels. In this case:
y=2x+1 subtract 1 from both sides
y-1=2x divide both sides by 2
(y-1)/2=x now just switch the labels for the variables...
y=(x-1)/2 so
f^-1(x)=(x-1)/2 is the inverse of f(x)=2x+1
Answer:
250 miles
Step-by-step explanation:
The given distance between the house and the beach is 125 miles.
Let 
miles be the distance between the house and the lunch stop.
So, at the time of the lunch stop, he already traveled miles, the remaining distance is the distance between the lunch stop and the beach.
Let 
miles be the remaining distance, so
Give that the ratio of the distance he has traveled, , to the distance he still has to travel, , is 
,i.e
Hence, the distance traveled by Herman when he stops for lunch is 250 miles.
