14.) find the slope and y-intercept of the line.
y = 7/5 x - 3

a.) 5/7 ; 3

b.) 7/5 ; - 3

c.) -3 ; 7/5

d.) 3 ; 7/5

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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
