Step-by-step explanation:
We are supposed to write an inequality to determine the number of hot dogs per minute Joey must eat for the last 9 minutes to break his record.
Let d represent the number of hot dogs Joey eats per minute for the next 9 minutes.
We have been given that after 1 minute, Joey has eaten hot dogs.
Hot dogs eaten in next 9 minutes would be 9 times d that is .
Total hot dogs eaten by Joey would be hot dogs eaten in 1 minute plus next 9 minutes: .
Since to break the record Joey needs to eat more than 72 hot dogs. We can represent this information in an inequality as:
Therefore, our required inequality would be .
The given function is
The inverse function is
To get the inverse, we swap each x and y coordinate.
The rule is
So that's why the point (0,1) becomes (1,0) for instance.
