Which pair of expressions are equivalent? 3v + 5 - 9v + 2 and negative 6v + 6

Negative 6n + 3 - 2n + 2 and negative 8 n + 6

Negative 4n + 8 + 9n - 2 and 5n + 6

10n - 5 - 2n + 3 and 5n - 2

whoever answers this gets 50pts pls hurry

The answer is -4n + 8 + 9n - 2. 3v + 5 - 9v + 2 = -6v +7. -6n + 3 - 2n + 2 = -8n + 5. 10n - 5 - 2n + 3 = 8n - 2.

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.
