Help me please
Y=2x+1
Y=-2x+1
Y= 2x-1
Y=-2x-1

i think its -2x+1

since it starts at 1, and decreases by 2 everytime you move

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
