Which expression is equivalent to the following complex fraction?
iVinArrow [24]

Answer:

Option B

Step-by-step explanation:

Numerator:

\dfrac{3}{x -1 }-4 =\dfrac{3}{x-1}-\dfrac{4*(x-1)}{x-1}\\\\

                 =\dfrac{3- 4x -4*(-1)}{x-1}=\dfrac{3-4x+4}{x-1}\\\\\\=\dfrac{-4x+7}{x-1} \:  \textbf{ [Combine like terms]}

Denominator:

2-\dfrac{2}{x-1}=\dfrac{2*(x-1)}{x-1}-\dfrac{2}{x-1}\\

                = \bf \dfrac{2x-2-2}{x-1}\\\\\\= \dfrac{2x-4}{x-1}\\\\= \dfrac{2*(x- 2)}{x-1}

\dfrac{\dfrac{3}{x-1}-4}{2-\dfrac{2}{x-1}}=\dfrac{\dfrac{-4x+7}{x-1}}{\dfrac{2*(x-2)}{x-1}}

                 \bf = \dfrac{-4x+7}{x-1}*\dfrac{x-1}{2(x-2)} \ \ \  \textbf{ [(x-1) in the numerator and denominator will be cancelled]}\\\\\\=\dfrac{-4x+7}{2(x-2)}

Which function has a vertex at the origin?
Crank

Answer:

B) f(x)=x(x-4)

Step-by-step explanation:

To find the function which has vertex at the origin.

Solution:

For a function to have its vertex at origin the function must pass through point (0,0) which means f(0)=0.

We will find f(0) for each of the given functions and check if it has vertex at origin.

To find f(0) we will plugin x=0 in the function.

A) f(x)=x+4

f(0)=0+4=4

Vertex is  not at the origin.

B) f(x)=x(x-4)

f(0)=0(0-4)=0  [Any number times zero is = zero]

Vertex is at the origin.

C) f(x)=(x-4)(x+4)

f(0)=(0-4)(0+4)=(-4)(4)=-16

Vertex is  not at the origin.

D) f(x)=2

f(0)=2

Vertex is  not at the origin.
