Answer:
I believe it is four dollars
You would need 1.5/4 cups
I believe the equation should be y = -0.5sin(x-2<span>π)-2</span>
You have to isolate x. First you start off by adding the like terms which is -3x and -x. By adding them you get -4x.
8 - 4x = 12
Then you subtract 8 on both sides since it is positive to isolate x.
-4x = 4
Then you divide -4 by both sides and get x=4/-4
4/-4 is simplified to -1 so the answer is x= -1
