Hi pls help last q.

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?

Are the corresponding angles congruent? explain why or why not.
