Write two linear functions, f(x) and g(x). for example, f(x) = 3x – 7 and g(x) = –2x + 5. then see whether f(x) – (–g(x)) is equivalent to f(x)+ g(x). hint: to find –g(x), just change the signs of all the terms in g(x). discuss whether you think your results would apply to every function.

The mean of a set of data is -3.82 and its standard deviation is 2.31. find the z score for a value of 3.99.

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

Merrida uses a pattern in the multiplication table below to find ratios that are equivalent to 7: 9. if merrida multiplies the first term, 7, by a factor of 6, what should she do to find the other term for the equivalent ratio? multiply 9 by 1. multiply 9 by 6. multiply 9 by 7. multiply 9 by 9.
