Use the factor theorem to determine if (x-4) . is a factor of x^5 - 3x^4 - x - 3

(x - 4) is not a factor because .

Step-by-step explanation:

According to the factor theorem, if f(x) = 0, only then f(x) can have a factor (x-a) which in this case is equal to (x - 4).

Considering this factor theorem, we can write it as:

Now to check if (x - 4) is its factor or not, substitute a value of 4 in place of x in f(x):

So f(x) is not equal to zero which means (x - 4) is not a factor of

step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
