In the pair of equations bx-6y=18 and 2x-3y=9,b is a constant. the system of two equations has infinitely many solutions. what is the value of b

If this system has infinitely many solutions, then one of the equations is a multiple of the other.

Compare:

bx-6y=18

2x-3y=9

Try this: Multiply all terms of the second equation by 2. We get:

4x - 6y = 18. To find b, set bx = 2x and simplify. We discover that b must have the value 2.

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
