What’s the linear equation in slope intercept form to (-3,7) and (6,-8)?
Aleonysh [2.5K]
Y= -5/3x + 2

To find slope:
-8-7 / 6 - (-3) = -5/3

Plug in x and y from one of the points to the equation to find b

7 = -5/3 (-3) + b

B = 2

Put it all together:

y = -5/3x + 2

Is the binomial a factor of the polynomial function?
olchik [2.2K]

Answer:

YES

NO

NO

Step-by-step explanation:

The given polynomial is: $ f(x) =  x^3 + 4x^2 - 25x - 100 $

(x - a) is a factor of a polynomial iff x = a is a solution to the polynomial.

To check if (x - 5) is a factor of the polynomial f(x), we substitute x = 5 and check if it satisfies the equation.

∴ f(5) = 5³ + 4(5)² - 25(5) - 100

        = 125 + 100 - 125 - 100

        = 225 - 225

        = 0

We see, x = 5 satisfies f(x). So, (x - 5) is a factor to the polynomial.

Now, to check (x + 2) is a factor.

i.e., to check x = - 2 satisfies f(x) or not.

f(-2) = (-2)³ + 4(-2)² - 25(-2) - 100

      = -8 + 16 + 50 - 100

     = -108 + 66

     ≠ 0

Therefore, (x  + 2) is not a factor of f(x).

To check (x - 4) is a factor.

∴ f(4) = 4³ + 4(4)² - 25(4) - 100

        = 64 + 64 - 100 - 100

        = 128 - 200

        ≠ 0

Therefore, (x - 4) is not a factor of f(x).

A wooden rod of 5 m 75 cm was cut into 5 equal pieces. What is the length of each piece.
hram777 [196]

We have: 5m 75cm = 5.75 m

So the length of each piece is : l = \frac{5.75}{5} =1.15

ok done. Thank to me :>
