Given: q = 7m + 3n, r = 11 - 2m, s = n + 5, and t = -m - 3n + 8.

simplify q + s - t.

-8m + 7n - 3
-8m - 7n - 3
8m + 7n - 3
8m - 7n - 3

If you would like to simplify Q + S - T, you can do this using the following steps:

Q = 7m + 3n, 
R = 11 - 2m, 
S = n + 5,
T = -m - 3n + 8

Q + S - T = 7m + 3n + n + 5 - (-m - 3n + 8) = 7m + 3n + n + 5 + m + 3n - 8 = 8m + 7n - 3

The correct result would be 8m + 7n - 3.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
