Given:
The function models the number of movie theaters in the United States t years after 1985.
To find:
The year in which the United States will have 35,000 movie theaters.
Solution:
We have,
Putting f(t)=35000, we get
Divide both sides by 750.
It means, United States will have 35,000 movie theaters 20 years after 1985.
Therefore, United States will have 35,000 movie theaters is 2005.
Answer:The b is 15.7-2(a)
Step-by-step explanation:
2a+b=15.7
b=15.7-2a
The length will be a+a which is greater than length of b
The b is 15.7-2(a)

Answer:
Step-by-step explanation:
Let represent number of tickets and represent the total cost to purchase them.
Now,assuming the relation to be of the form:
, where, and are constants.
Let us find and using the values from the table.
For, . So,
For, . So,
Subtract equation 1 from equation 2. This gives,
Now, plug in in equation 1 and solve for
Therefore, the relation between the number of tickets and total cost of purchase is given as:
Slope intercept form is y=mx+b. So let's use the given equation and turn it into this form.
Move the -3x to the right side
Divide both sides by -5
This should be your answer, let me know if you need any clarifications, thanks!
