Alex placed a small beaker of cold water on a hot plate and heated it for 10 minutes. He took the
temperature of the water several times during those
10 minutes and recorded his data. Alex claims that
the graph below shows the relationship between
temperature and time when water is heated.

I'm guessing that it is "An experimental error caused the graph to level off, because the water termpature should keep increasing over time."

Explanation:

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
