Which is the solution set of a for -3(-x + a) + 7 < 5 when x = -1?

a) a > - 1/3
b) a < - 1/3
c) a > 5/3
d) a < 5/3

C

Step-by-step explanation:

-3 (-1+a)+7 <5

3-3a+7 <5

-3a+10 <5 (collect like terms )

-3a <-10+5

-3a <-5(divide both side by -3)

-3a/-3 <-5/-3

a>5/3

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
