Fifty points! hurry! asap!
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

explain to the biologist how she can solve this on a graph using a system of equations.
*note that this question is an essay question.*
**you must solve this by using system of equation**
that's why it worths lots of points!

8000 + 8800 + 8000 + 8 million + 80 trillion + another a katrillion equals

In the geometric progression –3, 12, −48… what term is 3,072?
