Solve for the first variable in one of the equations, then substitute the result into the other equation.

Y = 2 y /3 − 3

x = − y /3 + 7

Hope this helped!

Find y in the line through (4,y) and (7,2) has a slope of 6

Alenkasestr [34]

Answer:

The value of y is -16.

Step-by-step explanation:

To find the missing coordinate, we can use the slope equation and plug in all known values.

m(slope) = (y2 - y1)/(x2 - x1)

6 = (y - 2)/(4 - 7)

6 = (y - 2)/-3

Now we can solve using cross multiplication.

y - 2 = -3*6

y - 2 = -18

y = -16

Identify the asymptotes and state the end behavior of the function f(x)=5x/x-25

AnnyKZ [126]

Using it's concepts, it is found that for the function $f(x) = \frac{5x}{x - 25}$ :

The vertical asymptote of the function is x = 25.

The horizontal asymptote is y = 5. Hence the end behavior is that $y \rightarrow 5$ when $x \rightarrow \infty$ .

<h3>What are the asymptotes of a function f(x)?</h3>

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.

The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity. They also give the end behavior of a function.

In this problem, the function is:

$f(x) = \frac{5x}{x - 25}$

For the vertical asymptote, it is given by:

x - 25 = 0 -> x = 25.

The horizontal asymptote is given by:

$y = \lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{5x}{x - 25} = \lim_{x \rightarrow \infty} \frac{5x}{x} = 5$
