Thread: elp for semester exams! please! :)

Classify each system as idependent, dependent or inconsistant:

x-3y=2
4x-12y=8

any help would be greatly appreciated! whenever i do it (through elimination) i get 0 = 10... what category does that come under?? but then again i might have that wrong aswell :P

0 = 10?? If you had to pick "consistent" or "inconsistent", which would you choose? Words still mean things in mathematics. You do not have to check your vocabulary at the door.

Both equations are the same. Multiply the first one by four. I'm not sure what makes a system of equations independent, dependent, or consistent, but that tidbit of information should help you.
