Use long division to determine the quotient of the polynomials. (x3 – 7x – 6) ÷ (x – 4) Which of the following options best desc

ribes the relationship between the polynomial division and the remainder?
a. The quotient has a remainder of zero. Therefore, the divisor is a factor of the dividend.
b. The quotient has a remainder of 9. Therefore, the divisor is not a factor of the dividend.
c. The quotient has a remainder of 30. Therefore, the divisor is not factor of the dividend.
d. The quotient has a remainder of 36. Therefore, the divisor is a factor of the dividend.

Answer:

The correct option is c.

Step-by-step explanation:

The quotient of the polynomials is

\frac{(x^3-7x-6)}{x-4}

We need to find the remainder by using long division method.

The dividend of the given expression is

Dividend=x^3-7x-6

Divisor=x-4

The long division method is shown below.

\frac{(x^3-7x-6)}{x-4}=(x^2+4x+9)+\frac{30}{x-4}

From the below attachment it is clear that the quotient has a remainder of 30. Therefore, the divisor is not factor of the dividend.

Therefore the correct option is c.

Consider the linear function f(x)=4x-5 Find the values of x for which f(x)=3,f(x)=5,f(x)=-3
Evgesh-ka [11]

Answer:

f(2) = 3

f(5/2) = 5

f(½) = -3

Step-by-step explanation:

Given the linear function f(x) = 4x - 5:

<h3>f(x) = 3</h3>

3 = 4x - 5

3 + 5 = 4x - 5 + 5

8 = 4x

8/4 = 4x/4

2 = x

Therefore, when f(x) = 3, x = 2.

<h3>f(x) = 5</h3>

5 = 4x - 5

5 + 5 = 4x - 5 + 5

10 = 4x

10/4 = 4x/4

5/2 = x

Therefore, when f(x) = 5, x = 5/2.

<h3>f(x) = -3</h3>

-3 = 4x - 5

-3 + 5 = 4x - 5 + 5

2 = 4x

2/4 = 4x/4

½ = x

Therefore, when f(x) = -3, x = ½.

Billy has x marbles. Write an
babymother [125]

Answer:

Charlie = 5 + x

Danny = x - 8

Eric = 3x

Step-by-step explanation:

Given

Billy's Marble = x

Required

Determine a,b and c

a. Charlie's Marble

"5 more" means 5 + or + 5

Since Billy's Marble is represented with x, then Charlie's Marbles will be

Charlie = 5 + x

b. Danny's Marbles

Having "8 fewer" means we have to subtract 8 from Billy's marble;

Since Billy's Marble is represented with x, then Danny's Marbles will be

Danny = x - 8

c. Eric Marbles

Having "three times as " means we have to multiply Bill's marble by 3;

Since Billy's Marble is represented with x, then Danny's Marbles will be

Eric = 3 * x

Eric = 3x

taurus [48]
To find the mean you must add up all the numbers and divide by how many there are:
35 + 60 + x
_________  =    70
        3

35 + 60 + x = 210

x = 65

He must score at least a 65 for a 70 average.
