Solve –2 + x > 10 using the properties of inequalities.

Using the properties of inequalities:
Subtract -2 from each side of the inequality    -2 + x > 10
Remember -2 - -2 becomes -2 + 2 = 0          - -2 + x > --2
10 - -2 becomes 10 + 2 =12                             0 + x > 12
So the final solution would be x > 12.
Therefore x would have to be all numbers greater than 12.
                                                    

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.
