Answer:

y = $\frac{1}{3}$ x + 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + y = 4 ( subtract 3x from both sides )

y = - 3x + 4 ← in slope- intercept form

with slope m = - 3

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-3}$ = $\frac{1}{3}$

Given c = 2 , then

y = $\frac{1}{3}$ x + 2 ← equation of perpendicular line

(2x^4 - 6x^2+8) + (-x^4+ 2x^2-12)

Neko [114]

(2x^4 - 6x^2+8) + (-x^4+ 2x^2-12)
=2x^4-6x^2-x^4+2x^2-12
=x^4-4x^2-12

Just watch your signs when opening up the brackets and then collect like terms.
