IS ANYONE SMART?? bc i need help

x ≤ 3

Step-by-step explanation:

5x-19≤ - 4 (starting equation)

first you add 19 on both sides of the inequality:

5x-19≤ - 4

   +19  +19

This isolates the variable so we have: 5x ≤ 15

Next you divide by 5 to get  x by itself: 5x÷5 ≤ 15÷5

Finally you solve and you should get: x ≤ 3

hope this helps :)

step-by-step explanation:

sry but any answer choices

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
