Answer:
slope: 2/5
Step-by-step explanation:
Answer:
b and d
Step-by-step explanation:
3/8 * 6/7
6*3=18
8*7=56
18/56 simplified is 9/28
Answer: D
Step-by-step explanation:
To find the difference, we want to make sure both denominators are equal.

Now that the denominators are equal, we can distribute and multiply out.

With the fractions multiplied out, we can actually put it into one large fraction.

Let's subtract the top expression.

This may seem like our final answer, but we can actually factor out an 3x in the numerator and denominator.

With the 3x factored out, they cancel out because 3x/3x=1.
Our final answer is:

Answer:
See the graph and explanation below.
Step-by-step explanation:
For this case we have the following function:

The domain for this function is given by:
since the natural log is not defined for negative numbers
, 
We can calculate some points in order to see the tendency of the graph, we can select a set of points for example
and we can calculate the values for f(x) like this
x=5.5

x=6

That represent the x intercept
x=7

x=8

x=9

x=10

And that represent the x intercept
And then we can see the plot on the figure attached.
