Solve the equation for x
-8 + 5x - 9 = 6

-11/5 hope that is right

First you had to add everything but 5x to other side of the equal sign. You do this by doing the inverse operation

Then after you do that you should I have 5x=23

You divide 5 by both sides your answer will be X=4.6

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.

I’m pretty sure the * means multiplication. so, if you multiply 5*1, it would equal 5. they are basically are-writing 5x1 as 5*1. so they would be… 5 10152025303540455055
