The music department orders 4 times as many Rock CDs as Jazz CDs. If the department orders 550. CDs, how many of CDs are rock?​
jek_recluse [69]

Answer:

440 Rock CDs

Step-by-step explanation:

Let number of rock CDs be "r", and

number of Jazz CDs be "j"

4 times as many Rock as Jazz, so we can write:

r = 4j

Total of 550 CDs, thus we can write equation 2:

r + j = 550

Now we replace 2nd equation with 1st equation and find j first:

r + j = 550

4j + j = 550

5j = 550

j = 550/5

j = 110

Now, finding r:

r = 4j

r = 4(110)

r = 440

There are 110 Jazz CDs and 440 Rock CDs

1. Find the slope of the line passing through (-3,-4) and (-6,-2).
r-ruslan [8.4K]

Answer:

slope = - \frac{2}{3}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 3, - 4) and (x₂, y₂ ) = (- 6, - 2)

m = \frac{-2+4}{-6+3} = \frac{2}{-3} = - \frac{2}{3}
