Answer:
8
Step-by-step explanation:
A = 64 musicians
A*5/8 = 40 guitarists
Jazz: x
Classic: y
x=4y
x + y = 40
5y = 40
y = 8
Answer:
The lines are parallel.
Step-by-step explanation:
Given the lines
![-2x-3y=9](https://tex.z-dn.net/?f=-2x-3y%3D9)
![4x+6y=24](https://tex.z-dn.net/?f=4x%2B6y%3D24)
Writing the equations in the slope-intercept form
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where m is the slope and b is the y-intercept
![-2x-3y=9](https://tex.z-dn.net/?f=-2x-3y%3D9)
![y=-\frac{2}{3}x-3](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B2%7D%7B3%7Dx-3)
Thus, the slope = m₁ = -2/3
also
![4x+6y=24](https://tex.z-dn.net/?f=4x%2B6y%3D24)
Thus, the slope = m₂ = -2/3
- We know that parallel lines have equal slopes
As
m₁ = m₂
Thus, the lines are parallel.
