I'm so sorry you have to take this X( I'm doing something really similar <3
First step is to distribute: -6a-6b+9a+9b
then simplify: 3a+3b
3(5+7) is the problem you are looking at. To figure it out, you can use properties. On the right side of the equals sign, it shows a property you can use to do the problem. In this case, they are distributing.
Answer:
y = 5 sin (2x) + 4
Step-by-step explanation:
this is sines function,
the amplitude is [9 - (-1)]/2 = 10/2 = 5
the period is 2πx/π = 2x
the x-axis of actual function is at y = 4
so, the function is :
y = 5 sin (2x) + 4
Answer:
See below.
Step-by-step explanation:
I would use cot x = cos x / sin x:
csc x sec x cot x
= csc x * 1/cos x * cos x / sin x
The cos x disappears:
= csc x * 1 / sin x
= csc^2 x.
