A system of equations is shown. - x + 3y = 9
x = 1 - 2y
What is the solution of the system?
A. (-19, 10)

B. (-6, 7/10)

C. (-9/2, 9/2)

D. (-3,2)

i think is g(1)=-1.

hope that i can

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

there is nothing below so i cannot
