Question

A biologist is comparing the growth of a population of flies per week to the number of flies a lizard will consume per week. She has devised an equation to solve for which day (x) the lizard would be able to eat the entire population. The equation is 3^x = 5x − 1.

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

Answer 1

I don't understand what it means by "solve this on a graph using a system of equations".

Answer 4

it means graph each function and find the intersection point. The x value will be the day, the y value is the population.

so you'll graph y = 3^x and and y = 5x - 1 on the same grid

Answer 5

thank you :)
