Answer:
2 and 3.
Step-by-step explanation:
2. and 3.
the total number of paintings depend upon the number of weeks that have passed as she adds 3 paintings every week to her collection.
1. can't be an option as output values depend upon the input values and hence not independent
4. can't be an option because each week that passes she adds 3 more paintings and since one input has 3 outputs, its not a function.
5. the number of weeks is the input value and number of paintings is the output value as you can later SEE how many paintings she has, not how many weeks it took her.

[g o f o h](-5) means the same as g(f(h(-5)))
Just like a normal math problem you start at the inner most part—h(-5). Then use the answer(-2) for the next inner part—f(-2). Finally that answer is used for the outer most part—g(-3). Which comes to -6.
Answer:
C. 150
Step-by-step explanation:
The given angle and angle x are supplementary. This means that when added together they add to 180. So, to solve you can set up an algebraic equation like 180=x+30. Then, subtract 30 from both sides to get 150=x.
