Sonic’s Drive-In Burgers had a Classic Car Cruise one night. They played oldies music, the servers wore roller skates, and there were 152 classic cars on display. Josie, the restaurant owner, played a game with the car owners. First everyone was told to turn their headlights on. Then Josie counted every other car (the 2nd, 4th, 6th, and so on), and told them to turn their headlights off. After that Josie counted every 3rd car (3rd, 6th, 9th, and so on). Those car owners were told to turn their headlights on If they were off, and turn their headlights off if they were on. She continued in this way, counting by every number (by 4’s, then by 5’s, then by 6’s, etc.) until she had finished counting by 152’s (which didn’t take long, since that’s how many cars there were.) As she counted, every car she pointed to reversed their lights from off to on or vice versa. When she was done, which cars still had their lights on?
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.
