A. -5 < y < -3 is the correct answer.
It skips by 6 if that's what you mean
Answer:
3cos(x)
Step-by-step explanation:
use cot(t) = 1/tan(t), transform the expression:
3tan(x)cos(x)x1/tan(x)
reduce the expression with tan(x):
3cos(x)
Answer is (9, 7)
Step by step
Rule: 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x).
This means, we switch x and y and make x negative.
So
(-7, 9) ➡️ ( 9, 7)
