Select all equations whose graphs have a vertex with x-coordinate 2. ny=(x-2)(x-4)
D y = (x - 2)(x + 2)
y= (x - 1)(x - 3)
y = x(x + 4)
y = x(x-4)

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
