Given: sintheta=5/13
Find sin: 2theta

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

If f(x)=1/x and g(x)=x+4 which of the following is the graph

If you double the input of a function and it results in twice the output and if you triple the input and it result in three times the output what can be guessed about the function?
