A biologist is comparing the growth of a population of flies per week to the number of flies a bullfrog will consume per week. She has devised an equation to solve for which day (x) the bullfrog would be able to eat the entire population. The equation is 2^x = 3x  1. However, she has observed that the bullfrog cannot eat more than seven flies in one week.
Explain to the biologist how she can solve this on a graph using a system of equations. Identify any possible constraints to the situation.

Best ResponseYou've already chosen the best response.0I looked at that, and I still don't understand how they went from "2^x = 3x 1" to "y = _____" . I don't understand where the "y" came from.

Best ResponseYou've already chosen the best response.0I understand that, but how do they get "y" if it wasn't even in the equation in the first place?

Best ResponseYou've already chosen the best response.02^x = 3x  1 so then 2^x = y but y also equals "3x  1"?
