Answer:

Option D.

Step-by-step explanation:

The given function is

f\left(x\right)=\dfrac{3x^{2}-3}{x^{2}-4}

In this function the degree of numerator an denominator is same i.e., 2.

Horizontal Asymptotes: If the degree of numerator an denominator is same, then

\text{Horizontal asymptote}=\frac{\text{Leading coefficient of numerator}}{\text{Leading coefficient of denominator}}

\text{Horizontal asymptote}=\frac{3}{1}

\text{Horizontal asymptote}=3

Horizontal asymptote is y=3.

f(x)=3

\dfrac{3x^{2}-3}{x^{2}-4}=3

3(x^{2}-1)=3(x^{2}-4)

x^{2}-1=x^{2}-4

1=4

This statement is false for any value of x, therefore the graph does not cross the horizontal asymtote.

Vertical Asymptotes: Equate the denominator equal to 0, to find the vertical asymptotes.

x^2-4=0

Add 4 on both sides.

x^2=4

Taking square root on both sides.

x=\pm \sqrt{4}

x=\pm 2

Vertical asymptotes are x=2 and x=-2.

The graph has two vertical asymptotes and one horizontal asymptote.

Therefore, the correct option is D.

Answer:

A+6+A = 20

A = 7

Step-by-step explanation:

J = number of problems Juana completed

A = number of problems Andy completed

J+A=20

J = A + 6

Replace J with A+6 in the first equation

A+6+A = 20

2A +6 = 20

Subtract 6 from each side

2A +6-6 = 20-6

2A =14

Divide by 2

2A/2 = 14/2

A = 7

Here,
RQ/RP = RS/RT = QS/PT = 1/2


Using the values of QS and PT will give,

\frac{y}{y + 46}  =  \frac{1}{2} \\  \\  2y =y + 46 \\  \\  y = 46


Therefore y= 46 units.

On a car trip Sam drove m miles Kara drove twice as many miles as Sam and Darin drove 20 fewer miles than Kara in terms of m man
frutty [35]

Answer:

Darin drove '2m - 20' miles.

Step-by-step explanation:

We are given that Sam drove 'm' no. of miles.

As, it is also given that Kara drove twice as many miles as Sam. Therefore we get that Kara drove '2m' no. of miles.

Now, it is given that Darin drove 20 miles fewer than Kara .i.e. Darin drove '2m - 20' no. of miles.

Hence, in terms of m, Darin drove '2m - 20' miles.
