When two gears are mashed, The revolutions per minute (RPM) are inversely proportional to the number of teeth, as shown below. In one machine the RPM ratio of the large gear to the small gear is 5:8. The small gear has 225 teeth. In a second machine the largegear at 500 RPM and has 217 teeth. The small gear revolves at 700 RPM. RPM of large gear= number of teeth on small gear RPM of small gear= number of teeth on large gear Find the number of teeth on the large gear of the first machine. __ Find the number of teeth of the small gear of the second machine. __
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
