Simplify the expression: 5x + 8 – 13y – 4x – 18 + 16y
O A) x + 3y - 10
OB) x - 3y + 10
OC) 3y + 10
OD X - 3y

Ithink ghe answer to this question is b just trying to others

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.
