Mr. brown's class is collecting books for a book drive. they started with 2 books. on the first day, they had 6 books. on the second day they had 18 books. write an equation that models this situation. a) y = 4x + 2 b) y = 2(3)x c) y = 3x + 2 d) y = x2 + 2

The equation which models the equation is given by :

Step-by-step explanation:

Mr. Brown's class is collecting books for a book drive.

They started with 2 books.

Now, x is the number of days

A). y = 4x + 2

on day 1, x = 1

⇒ y = 6

On day 2 , x = 2

⇒ y = 10 but on day 2 Number of books he had is given to be 18

So, This option is rejected

on day 1, x = 1

⇒ y = 6

On day 2 , x = 2

⇒ y = 18

So, This option is correct

C). y = 3x + 2

on day 1, x = 1

⇒ y = 5 but on day 1 Number of books he had is given to be 6

So, This option is rejected

D). y = x² + 2

on day 1, x = 1

⇒ y = 3 but on day 1 Number of books he had is given to be 6

So, This option is rejected

Therefore, The equation which models the equation is given by :
