Answer:
Step-by-step explanation:
Answer:
line k is parallel
Step-by-step explanation:
because they will never intersect
Answer:

And then we can use for example the first point
to find the intercept:


So then the linear model for this case should be:

Step-by-step explanation:
For this case we want to find a linear model given by:

Where r = represent the number of readers , t= years after 2000
m = the slope for the model and b the intercept
For this case we can define the following points from the data given:
4 years after 2000
14 years after 2000
We can find the slope with the following formula:

And then we can use for example the first point
to find the intercept:


So then the linear model for this case should be:

Answer:
The Hardcover costs: $19.95 and the Paperback is: $6.65.
Step-by-step explanation:
6.65 * 3 = 19.95
19.95 + 6.65 = 26.60
