Students plug into the quadratic formula or try random ( x ) values. This takes 2 minutes.

A population of bacteria triples every 2.5 hours. If the initial population is 100, which equation represents the population ( P ) after ( t ) hours? A) ( P = 100(3)^t ) B) ( P = 100(3)^2.5t ) C) ( P = 100(3)^t/2.5 ) D) ( P = 100(3)^t + 2.5 ) A population of bacteria triples every 2

2x + 3y = 7 x - 2y = -3

: Hard problems often have a shortcut. If a problem looks like it will take 5 minutes of calculation, look for a basic principle (like the sum of roots ) that can solve it in 30 seconds. If a problem looks like it will take

( 3x + 4y = 14 ). ( 6x + 8y = c ). For what value of ( c ) does the system have infinite solutions?
