I have these three problems and I have to graph each side of each problem to see where they overlap each other. Could someone tell me what the amp, and period is for each one, and if there is any VS, HS or anything else.

1.) sin 2x = -sinx

2.) sinx = cos2x -1

3.) sinx = -cosx

Remember, you have to do it for each side(left and right hand side) of each problem.

i understand how to do systems of equations, but this one's a little complicated.
9a+7b=--30 (negative 30)
8b+5c=11
--3a+10c=73 (negative 3a)
when i solve this by elimination, it'll give me no solution, and when i solve it by substitution it'll give me infinite solution. and in the back of the book the answers are (--1,--3,7) a=--1, b=--3, c=7. i can't find an example for this in the book! please, somebody help me.

Which move faster?
comets or human built space probes?
I would guess comets.
Why don't we send out a probe. Land it on a comet. Have it take readings. Fly way out of our solar system.
Then when it comes back, we can get all of the data.
