How to show work for an equation that you can use is 198 +16x=326

16x=326-198
16x=128
x=128/16
x=8

Your equation is 198 + 16x = 326
first you will move the constant to the right side and change its sign
16x = 326 - 198
youll then subtract the numbers
16x = 128
youll now divide both sides of the equation by 16
x = 8
the answer to this equation is x = 8
let me know if you have any other questions

Your answer should be “b” i truly hope i could ! good luck (:

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.
