Answer: 
<u>Step-by-step explanation:</u>
Given: cos x =
, x is in Quadrant 4
Use Pythagorean Theorem to find sin x:
8² + y² = 17²
y² = 17² - 8²
y² = 289 - 64
y² = 225
y = 15
→ sin x = 
Use the double angle formula to find cos (2x):

Answer:
(w-2)x4 = p (i think)
Step-by-step explanation:
We have to get the y alone. So we'll subtract 3x on both sides.
Our new expression is y<-3x+8
