A library is buying books at a constant rate of 150 books per year. The equation y = 150x + 7000

gives the amount of books in the library, where y is the number of total books and x is the number of years. Which statement is true?

The answer is C

Step-by-step explanation:

I think C because the question stated, "A library is buying books at a constant rate of 150 books per year." This cancels out all other options.

A said that they are purchasing 7,000 books per year. They were actually purchasing 150 books per year.

B said that they were purchasing 150 books per month. 150 x 12 = 1,800, which meant that at this rate, 1,800 books would be bought per year. That is not true with what the question says.

D said that they were purchasing 7,000 books per month. It is not possible for the library to buy more books per month than per year.

This is why I think the answer is C.

P.S.   I am writing long responses because I want to get marked braniest, so please mark this as brainest :)

C

Step-by-step explanation:

The answer is C, because X is per year, so its 150 books per year, and the library already had is 7000 bc your adding that number to the amount of books your going to buy per year

Tyler ran 0.06 miles farther than Elena

Step-by-step explanation:

From the graph we can find the distance ran by Tyler in 10 minutes is approximately 1.24 miles

Given the equation for Elena's distances and times is

y=8.5x, where x is the distance in miles and y is the time in minutes, we can know the value of x when y = 10 minutes

miles

With this numbers at hand, we can infer Tyler ran 1.24 - 1.18 = 0.06 miles farther than Elena
