Hector works 12 hours per week at a part time job. His original pay rate was $8.00 per hour, but he recently received a raise of x dollars per hour. His new total weekly pay, y, is represented by the equation y=12(8+x). If hector earned $126 last week, what was the amount of hectors raise per hour?

Ibelieve the answer would be 7, 13, 23

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
