Solve each system by substitution. 1) y = 6x – 11 - 2x - 3y=-
what does the variable y equal to

The correct answer would be d.(0,5)

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.

i believe it's a.

i'm not sure on this one, most likely correct.

good luck!
