Write y=x^2+16x−7​ in vertex form. Then identify the vertex.
WARRIOR [948]

The vertex form of the function is y = (x + 8)² - 71

The vertex is (-8 , -71)

Step-by-step explanation:

The vertex form of the quadratic equation y = ax² + bx + c is

y = a(x - h)² + k, where

  • (h , k) are the coordinates of the vertex point
  • a, b, c are constant where a is the leading coefficient of the function (coefficient of x²) , b is the coefficient of x and c is the y-intercept
  • h=\frac{-b}{2a}
  • k is the value of y when x = h

∵ y = x² + 16x - 7

∵ y = ax² + bx + c

∴ a = 1 , b = 16 , c  = -7

∵ h=\frac{-b}{2a}

∴ h=\frac{-16}{2(1)}

∴ h = -8

To find k substitute y by k and x by -8 in the equation above

∵ k is the value of y when x = h

∵ h = -8

∴ k = (-8)² + 16(-8) - 7 = -71

∵ The vertex form of the quadratic equation is y = a(x - h)² + k

∵ a = 1 , h = -8 , k = -71

∴ y = (1)(x - (-8))² + (-71)

∴ y = (x + 8)² - 71

∵ (h , k) are the coordinates of the vertex point

∵ h = -8 and k = -71

∴ The vertex is (-8 , -71)

The vertex form of the function is y = (x + 8)² - 71

The vertex is (-8 , -71)

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
