A system of equations has 1 solution. If 4x - y = 5 is one of the equations, which could be the other equation? y = -4x + 5
y = 4x-5
2y = 8x -
-2y = -8x - 10

you should at least use a calculater

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
