distance = distance
50x = 55(x-(1/2)
50x = 55x - (55/2)

Graph the function f(x) = x2 + 5x − 6 / x + 1 showing all the key features.

Vedmedyk [2.9K]

Answer:

the attached image shows the graph for given equation.

Step-by-step explanation:

We are given the following equation in the question:

$f(x) = x^2 + 5x - \displaystyle\frac{6}{x} + 1$

The attached image shows the graph for the given equation.

We could plot this graph by finding the coordinated for different values of x.

Vertical asymptotes:

$x = 0$

There are no horizontal asymptotes.

Some points on graph are:

(-3,-3), (-2,-2), (-1,3), (1,1), (2,12), (3,23)

Answer:

D. 120°

Step-by-step explanation:

Interior angles of a rhombus always add up to 360 degrees. Thus we can set up an equation:

g+g+2g+2g=360

Now let's combine all the like terms (g's).

6g=360

Now we divide both sides by six to isolate g.

g=60

We can now substitute g into angle B, to find its value.

2(60)

120

Thus, the measure of angle B is 120, or option D.
