My sister needs help with this problem !!

Can you post step by step

Thank you!

Step-by-step explanation:

the inequality says that x needs to be less than or equal to 2, we know the first number in an ordered pair is x-axis the only number less than 2 is -2

(-2, 1)

Step-by-step explanation:

The only ordered pair with the x position (the left one) less than or equal to -2 is the third one where x = -2.

All other possible answers have x as positive values so they are all x > -2 and do not meet the test

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
