Answer:

  • See below

Step-by-step explanation:

<u>The roots are:</u>

  • 3, 3, 2 - 3i, 2 + 3i (conjugate of 2 - 3i should be added) and the leading coefficient is - 5

<u>The polynomial is:</u>

  • -5(x - 3)² (x - [2 - 3i]) (x - [2 + 3i]) =
  • - 5(x² - 6x + 9) (x² - 4x + 13) =
  • -5(x⁴ - 10x³ + 46x² - 114x + 117) =
  • -5x⁴ + 50x³ - 230x² + 570x - 585

Opportunity to get Brainliest! I will put various questions and will mark BRAINLIEST!
Hatshy [7]

Answer:

parallel

Step-by-step explanation:

Parallel lines have equal slopes.

Calculate the slopes m using the slope formula

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

with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (2, 3)

m = \frac{3-2}{2+1} = \frac{1}{3}

Repeat with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 1)

m = \frac{1-0}{3-0} = \frac{1}{3}

Since slopes are equal then parallel

slope intercept form of equation of a line that passes through (-3,8) y=-2/3x+6 what is the point slope equation for this line??
nlexa [21]

Answer:

\large\boxed{y-8=-\dfrac{2}{3}(x+3)}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

We have the equation of a line in the slope-intercept form

y=-\dfrac{2}{3}x+6\Rightarrow m=-\dfrac{2}{3}

and the point (-3, 8).

Substitute:

y-8=-\dfrac{2}{3}(x-(-3))\\\\y-8=-\dfrac{2}{3}(x+3)
