Translate the sentence into an equation using n to represent the unknown number. Then solve the equation for n. a number subtracted from 46 is -21
a
46-n=-21
n - 67
b.
46-21 = 1
n = 67
C.
46 - 21 = n
n = 25
d.
46-n--21
n = 75

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.
