Choose the answer based on the most efficient method as presented in the lesson. If the first step in the solution of the equation -9 + x = 5x - 7 is "subtract x," then what should the next step be? add 7 add 9 subtract 5x

For me i think it'll land on blue

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.

Where is the rest of the question
