Which answer describes the solution to each equation?

anonymous · Answer

They are all one solution because they are one variable (x) functions.

anonymous · Answer

If you have two variable functions (x),(y) you can have infinity number of solutions

K12 says that was wrong @OdinMW 

For them, the answers were:
1. C
2. A
3. C
4. B

Yes my apologies I didn't actually solve them. What you have to do is try to solve for x and If you get x =x then its infinity, if you cancel out the x then there is no solution, and if you can find a solution then you have one solution.

Thanks anyways, Odin! I still got a 80% on my test from the other questions.

Sorry bud, hope you understand it.
