Below is a set of equations. Sort the equations into 2 categories of your choosing. Then, sort the equations into 2 categories in a different way. Be prepared to explain the meaning of your categories. 100 = 8(x + 9) 9(x + 7) = 100 8(9 + x) = 100 (x + 7) * 9 = 100 100 = (9 + x) * 8 100 = 8x + 72 9x + 63 = 100 72 + 8x = 100 9x + 63 = 100 100 = 72 + 8x

If you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Acollection of coins has value of 64 cents. there are two more nickels than dimes and three times as many pennies as dimes in this collection. how many of each kind of coin are in the collection?

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297
