Answer:

  • a) y = 3/4x - 8
  • b) y = 1/7x + 7
  • c) y = -5/7x - 3
  • d) y = x + 8

Step-by-step explanation:

<u>Converting the equations from standard to slope-intercept form</u>

a)

  • 3x - 4y = 32
  • 4y = 3x - 32
  • y = 3/4x - 8

b)

  • x - 7y = -49
  • 7y = x + 49
  • y = 1/7x + 7

c)

  • 5x + 7y = -21
  • 7y = -5x - 21
  • y = -5/7x - 3

d)

  • x - y = -8
  • y = x + 8

Answer:

P(x) = x^4 -16x^3 +76x^2 -72x -100

Step-by-step explanation:

The two roots 1-√3 and 1+√3 give rise to the quadratic factor ...

... (x -(1-√3))(x -(1+√3)) = (x-1)^2 -(√3)^2 = x^2 -2x -2

The complex root 7-i has a conjugate that is also a root. These two roots give rise to the quadratic factor ...

... (x -(7 -i))(x -(7 +i)) = (x-7)^2 -(i)^2 = x^2 -14x +50

The product of these two quadratic factors is ...

... P(x) = (x^2 -2x -2)(x^2 -14x +50) = x^4 +x^3(-14 -2) +x^2(50 +28 -2) +x(-100+28) -100

... P(x) = x^4 -16x^3 +76x^2 -72x -100

What is the sum of the zeros of the function: y= x^2 - 5x + 6?
yawa3891 [41]

Answer:

Step-by-step explanation:

The zeros are the values of x for which y = 0

Quadratic formula

x = [5 ± √(5² – 4·1·6)] / [2·1]

 = [5 ± √1] / 2

 = [5 ± 1] /2

 = 2, 3

sum of zeros = 5
