$h-hour(s)\\min-minute(s)\\\\1h=60min\to45min=\dfrac{45}{60}h=\dfrac{45:15}{60:15}h=\dfrac{3}{4}h\\\\45min\ to\ 1h=\dfrac{3}{4}h:1h=\huge\boxed{3:4}$

First you need each side of the ratio to be in the same units.
The easiest way to do that is to convert 1 hour into minutes.
1 hour=60minutes
So your ratio is now 60:45
Now you need a common factor that goes into both 45 and 60.
15 is the greatest common factor so now divide each side by 15.
45÷15=3
60÷15=4
The ratio, in its simplified for is 4:3

Write the equations for all vertical horizontal asymptotes. Vertical asymptote(s):Horizontal asymptote(s):Find all x-intercepts

NISA [10]

We have the next graph

And we must find:

1. Vertical asymptote(s):

We can see that there is a vertical asymptote when x = 2.

So, the vertical asymptote is

$x=2$

2. Horizontal asymptote(s):

We can see that there is a horizontal asymptote y = -1

So, the horizontal aymptote is

$y=-1$

3. x-intercept(s) and y-intercept(s):

We can see the graph intercepts the x-axis when x = -6

So, the x-intercept is (-6, 0)

We can see the graph intercepts the y-axis when y = 3

So, the y-intercept is (0, 3)

4. Domain nd Range:

Domain: The domain is the set of numbers that we can take in x-axis for the function.

Since we have a vertical asymptote that is x = 2 and we don´t have any more vertical asymptote the domain will be all real numbers except the value of the asymptote. So, the domain is
