How do you divide polynomials using long division
levacccp [35]
This is a simple example:-
             x   +   9
         ------------------------------
x - 1 )  x^2  +  8x  -    9
           x^2  -   x                  subtract
           ------------
                     9x  -  9
                     9x  -  9
                  ----------
                     ..........

First divide x into x^2  to give x which goes above 
Then multiply x - 1 by x to give x^2 - x

Subtract this fro x^2 + 8x  gives 9x
Bring down the - 9 then divide x into 9x
and finally  multiply x - 1 by  9 to give   9x - 9
Finally subtract  and you sre done. There is no remainder as x - 1 is a factor of x^2 + 8x - 9.

The  polynomial must be in descending powers of x . If one is missing you insert it  with a coefficient of zero before you start the division. 

for example if you have   x^3 - 3x + 12   you write it as

 x^2 + 0x^2 - 3x + 12

The value of a dependent variable in a function is always blank the value of independent variable
jarptica [38.1K]

The value of a dependent variable in a function is always dependent on the value of an independent variable correct choice is dependent on.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The problem is incomplete.

The complete problem  is:

The value of the dependent variable in a function is always __ the value of the independent variable.

  • Greater than
  • Dependent on
  • Equal to
  • Less than

As we know In a function, the value of the dependent variable is always determined by the value of the independent variable.

Let's assume the function is:

f(x) = ax² + bx + c

Here a, b, and c are constant.

In the above function x is the independent variable and y is the dependent variable which is dependent on the value of x.

For every value of x we get a value of y.

Thus, the value of a dependent variable in a function is always dependent on the value of an independent variable correct choice is dependent on.

What is the equation in slope-intercept form of the line
Natali5045456 [20]

Answer:

y = (-4/3)x + 4  

Step-by-step explanation:

Let y = mx + b, be the equation of the line in slope intercept form where we need to find m and b.

Perpendicular to y = (3/4)x - 5, means that m = - (1 / (3/4) ) = - 4/3

So, at this point, y = (-4/3)x + b.

Crossing the x - axis at 3 means that (3, 0) is a point on the line, where we note that x=3 and y=0.

Thus, we plug in these values into the equation y = (-4/3)x + b, to get

0 = (-4/3)(3) + b

0 = -4 + b, so that

b = 4.

Hence, the answer is:

y = (-4/3)x + 4
