Write an equation in slope intercept form for a line perpendicular to the line
konstantin123 [22]

Answer:

y=(1/3)x- 4/3

Step-by-step explanation:

If two lines are perpendicular to each other, then the slopes will be the negative inverse to each other.

Example:

the negative inverse of 2 is -1/2

the slope of  y=-3x+2  is -3

the negative inverse of -3 is \dfrac{1}{3}

So we have the perpendicular line be :y=\dfrac{1}{3}x+b

Since it also go through (4,0)

plug in we get 0 = \dfrac{4}{3}+b

b=-\frac{4}{3}

So the equation would be

y=\frac{1}{3}x - \frac{4}{3}

Step-by-step explanation:

\text{Use FOIL:}\\\\(a+b)(c+d)=ac+ad+bc+bd

(x+4)(2x^2-3x+5)\\\\=(x)(2x^2)+(x)(-3x)+(x)(5)+(4)(2x^2)+(4)(-3x)+(4)(5)\\\\=2x^3-3x^2+5x+8x^2-12x+20\\\\\text{combine like terms}\\\\=2x^3+(-3x^2+8x^2)+(5x-12x)+20\\\\=2x^3+5x^2-7x+20
