F(x)= x^3-4x^2+9 and let g(x)=6x^3+x^2-5x-12 what is f(x)-g(x)

Anarel [89]

$f(x) - g(x) = -5x^3-5x^2+5x +21$

Step-by-step explanation:

Given functions are:

$f(x) = x^3-4x^2+9\\g(x) = 6x^3+x^2-5x-12$

We have to find the difference of functions

So,

$f(x) - g(x) = x^3-4x^2+9 - (6x^3+x^2-5x-12)\\= x^3-4x^2+9-6x^3-x^2+5x+12$

Combining like terms

$x^3-4x^2+9-6x^3-x^2+5x+12\\=x^3-6x^3-4x^2-x^2+5x+9+12\\= -5x^3-5x^2+5x +21$

Hence,

$f(x) - g(x) = -5x^3-5x^2+5x +21$

-2x + y=5 and -5x + y = -4 cooridbnates of the solution to this system of equation

Viktor [21]

Answer:

(3,11)

Step-by-step explanation:

Turn both equations into linear equations:

y=2x+5

y=5x-4

Then, just graph both equations.

Find the point where the two lines intersect. That point of intersection is the solution. That coordinate is (3,11).
