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 2x = 3x − 1.

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

@.Mehek. Help?

seb.cal · Answer

I just need help with the math concept of this problem, not the explaining.

.mehek. · Answer

For system of equations, I thought you needed at least 2 equations o.o

seb.cal · Answer

Same. Because the answer lies where they intersect...

seb.cal · Answer

But this one only has one so I'm just like, "Huhhh?"

.mehek. · Answer

Oh wait. . . there are two equations XD

y = 2x and y = 3x - 1

I didn't see that there was an equal sign in between

.mehek. · Answer

is it 2x or $2^x$?

seb.cal · Answer

OOHH! I saw that, but didn't realize it was 2 separate equations. It's an 'x' raised as an exponent.

.mehek. · Answer

So I guess you just graph both of these and find the solution?

seb.cal · Answer

Okay, I'll do that :) Thanks for helping me out, I thought it was just one equation xD
