Find the value of two numbers if their sum is 70 and their difference is 36.

A+b=70
a-b=36
a=36+b
36+b+b=70
2b+36=70
2b=34
b=17
a=53. As a result, the two numbers are 17 and 53. Hope it help!

Idon't know what's the answer lol

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.
