Is (x+1) a factor off (x)=x3+x2−4x−4? <br><br> A) Yes<br> B) No
satela [25.4K]

Remainder theorem again...

p(x)=x^3+x^2-4x-4

p(-1)=(-1)^3+(-1)^2-4(-1)-4=0

So Yes, x+1 is a factor.

Fred has a bag of coin with only nickels and quarters. He got $20 by
Sedbober [7]

Answer:

75 quarters 25 nickels

Step-by-step explanation:

q=quarters n=nickels

q+n=100   n=100-q

0.25q +0.05(100-q)=20

From now I will multiply  by 100 to avoid decimals

25q + 5(100-q)=2000

20q=1500

q=75       n=25

75*0.25= 18.75

25*0.05=1.25

18.75+1.25=20

The graph of a linear function passes through the points (-1, -1/4) and (1, -3/4). Which equation represents the function ?
lyudmila [28]

The equation of the line will be given as y = -4x - (- 17/ 4).

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.


Given that:-

  • The graph of a linear function passes through the points (-1, -1/4) and (1, -3/4).

The equation of the line will be given as:-

y  -  y₁ = m ( x  -  x₁)

slope m will be calculated as:-

m =\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1+1}{\dfrac{-3}{4}+\dfrac{1}{4}}=-4

The equation will be:-

y  -  (1/4)  =  -4( x +  1 )

y  = -4x  -  (17/4)

Therefore the equation of the line will be given as y = -4x - (- 17/ 4).

Which of the following shows the division problem below in synthetic division
alexandr402 [8]

Answer:

The Answer is C

Step-by-step explanation:

Look at each coefficient next to the degree of the radical. When inputting that number for synthetic division (From greatest degree to least) you would get 8 1 and -5. The number that is the divisor is the 6, but you have to set (x - 6) to equal zero, which would get you a number of 6.
