You have to plug in the numbers for x and then solve.
For example, when it says y=2x-4, you put -2 and the numbers below it for x and then solve.
(I don't want to give you the answer to everything and want to help you understand how to do it.)
The last two choices are appropriate.
Both give you f(1) = 7, f(2) = 9.50, f(3) = 12.00, ... as they should.
Answer:
90 seconds
Step-by-step explanation:
If James eats 32 hotdogs in 60 seconds, we want to find how long it would take James to eat 48 hotdogs.
We can use proportion to solve this problem.
If 32:60, then 48:x.
Since it will required more seconds to eat 48 hotdogs, 32 will divide.
If more, less divides.
Therefore


Therefore it will take James 90 seconds if he eats at the same rate
I think it will take 50 minutes because it is in the middle of 40 and 60
