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 3x = 5x − 1. Explain to the biologist how she can solve this on a graph using a system of equations.

To solve the equation 3x = 5x - 1 graphically, graph y=3x and y=5x-1 on the same plane and find their intersection.

To solve the equation 3^x = 5x - 1 graphically, the biologist would graph y = 3x and y = 5x-1 on the same plane and find their intersection,

Two gears are connected and are rotating simultaneously. The smaller gear has a radius of 3 inches, and the larger gear has a radius of 7 inches. two circles touching at one point. Larger circle has radius of 7 inches. Smaller circle has radius of 3 inches. Part 1: What is the angle measure, in degrees and rounded to the nearest tenth, through which the larger gear has rotated when the smaller gear has made one complete rotation? Part 2: How many rotations will the smaller gear make during one complete rotation of the larger gear? Show all work.

You can look at this :) http://openstudy.com/study#/updates/53403986e4b05a4f7d541f17 when the small circle has mad e one rotation the larger one has made 4/7 of a complete rotation so the larger one has rotated 4/7 * 360 dgrees

(one complete rotation = 360 degrees)

yeah but thats only for part 1
