Answer:y=-1/5-x
Step-by-step explanation:
I think you are right so far what i've done comes out to your answer.
Hopefully this file will help you solve your problems. Please let me know if you have anymore questions. :)
Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2
Your answer should be 48x when you've completely simplified, but since we were not provided with answer choices to choose from, I cannot be for sure (unfortunately). :/ If 48x is one of your answer choices, than my answer is right! :)
