Answer:  The correct option is (B) x^2-2x+4.

 

Step-by-step explanation:  We are given to find the following quotient:

Q=(x^3+8)\div(x+2)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We know the following algebraic formula:

x^3+a^3=(x+a)(x^2-ax+a^2).

So, we have

x^3+8\\\\=x^3+2^3\\\\=(x+2)(x^2-x\times2+2^2)\\\\=(x+2)(x^2-2x+4).

Therefore, from equation (i), we have

Q\\\\=(x^3+8)\div(x+2)\\\\\\=\dfrac{x^3+8}{x+2}\\\\\\=\dfrac{(x+2)(x^2-2x+4)}{(x+2)}\\\\=x^2-2x+4.

Thus, the required quotient is x^2-2x+4.

Option (B) is correct.

charle [14.2K]

Answer:

-2

Step-by-step explanation:

The equation is -12/c=6

by solving for c you get,

-12/c=6

Then multiply both sides by the LCM c to get, -12=6c

Divide both sides by 6 to get,

-12/6=6c/6

-2=c

Verification:

-12/-2=6 since when a negative number divides a negative number the answer is a positive value

Slope =<br> ; y-intercept = -3
Goshia [24]

Question is incomplete Let assume the Slope = 2

Answer:

Therefore the Equation of line is

y=2x -3

Step-by-step explanation:

Given:

Slope = 2 ( Assumption )

y-intercept = -3

To Find:

Equation of Line in Slope-intercept form

Solution:

Equation of Line in Slope-intercept Form is given as

y=mx+c

Where,

m=Slope\\c=y-intercept

So, substituting Slope =2 and y-intercept = -3 in above we get

y=2\times x -3 Which is the Required Equation of line

Therefore the Equation of line is

y=2x -3
