Answer:
-5k-10
Step-by-step explanation:
- k + 2 (- 2k - 5) = - k - 4k - 10 = - 5k - 10
Answer:
A. -10
B. -1
C. 5
Step-by-step explanation:
A. 3x-4 = 3(-2)-4 = -10
B. 3x-4 = 3(1)-4 = -1
C. 3x-4 = 3(3)-4 = 5
Step-by-step explanation:
The point (12, 5)
x = 12, y = 5
=> r =√12²+5² =√144+25= √169=13
so, cos θ = x/r = 12/13 and
cot θ = x/y = 12/5
