If x + 12 ≤ 5 − y and 5 − y ≤ 2(x − 3), then which statement is true? a. x + 12 ≤ 2(5 − y) b. x + 12 ≤ 2x − 3 c. x + 12 ≤ 2(x − 3) d. x + 12 ≤ y − 5

The answer is c. 7 (i think) i’m almost sure though

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.
