The inverse of F(X) is a function.
For something to be a function, a vertical line must not intersect the graph more than once. Since, the horizontal line doesn't intersect the F(X) graph twice, this means that the vertical line won't intersect with the inverse of the graph
Answer:
Hence, the equation that represents the number of songs she will have after 104 weeks is:

Step-by-step explanation:
It is given that:
originally had 47 songs but plans to purchase 3 new songs each week. She wants to know how many songs she will have after 104 weeks.
Based on the data we see that:
Initial number of songs she has:

The number of songs she will have after second week is:

After Third week:

and so on:
After 104 weeks she will have:

Hence, option: C is the correct answer.
( This could also be seen as it form an arithmetic progression with initial term as a=47 and common difference i.e. d=3
Hence, the nth term is given by:

)
the answer is 2.86 dollars because it is 2.8 times 2.55 and subtract that from 10.
Answer:
Step-by-step explanation:
In this scenario, Octavia should buy at least 12 small milkshakes. At $2.50 each small milkshake, buying 12 would be a total of $30. Since she needs to buy atleast 20 total milkshakes, she would need to buy 8 large milkshakes which at $6 each would cost her a total of $48. Together this would sum up to be $78 for the 20 milkshakes which would mean that Octavia is still under her budget.
