cos(3x) = cos(2x+x)
= cos(2x) cos (x) -sin(2x)sin(x)
Answer: Choice #2
Step-by-step explanation: The slope of -1/4 means that the line is ascending to the left, which rules out the first and last choice. The y-intercept of -3 means that it crosses the y-axis at (0,-3). This is why it is #2.

the difference from 40000 to the future value in 2020, namely 5 years later is simply the yield or interest amount.
Answer:
x=8 x=-2
Step-by-step explanation:
|x-3| -10=-5
Add 10 to each side
|x-3| -10+10=-5+10
|x-3| =5
Now separate into two equations , one positive and one negative
x-3 = 5 x-3 = -5
Add 3 to each side
x-3+3 = 5+3 x-3+3 = -5 +3
x=8 x=-2
