What is the perpendicular slope to 6/-3

IRISSAK [1]

Answer:

Perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

Step-by-step explanation:

Given:

Let the perpendicular slope be x.

The given slope is $\frac{6}{-3}$

For perpendicular slopes, the product of the slopes is equal to -1.

Therefore, $x\times \frac{6}{-3}=-1\\-\frac{6}{3}x=-1\\6x=3\\x=\frac{3}{6}=\frac{1}{2}$

Therefore, the perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

F(x)=x^3-2x+6 g(x)=2x^3+3x^2-4x+2 Find (f-g)(x).

____ [38]

(f-g)(x) = f(x) - g(x)
= (x^3 -2x+6) - (2x^3+3x^2-4x+2)
= x^3 -2x +6 -2x^3 -3x^2 +4x -2 . . . . distribute the negative sign
= (1-2)x^3 -3x^2 +(-2+4)x +(6-2) . . . . . combine like terms

(f-g)(x) = -x^3 -3x^2 +2x +4
