Question

A biologist is comparing the growth of a population of flies per week to the number of flies an iguana will consume per week. He has devised an equation to solve for which day (x) the iguana would be able to eat the entire population. The equation is 3x = 2x + 1.

Explain to the biologist how he can solve this on a graph using a system of equations.

Answer 5

I'm not really sure how I can guide you or have you participate so I'll simply try to explain the concept which the question is testing you on.

The equation is 3x = 2x + 1

He can solve this on a graph by having the following two equations:

y = 3x
y = 2x + 1

Since we have two equations with y = something, we simply set them equal to each other. And that's how we got 3x = 2x + 1.

So, now, explain, in your own words, how the biologist can solve 3x = 2x + 1 by graphing it using a system of equations. :)

3x = 2x + 1
x=1
