Answer matt had 5 library books. he checked 1 additional book out every week without returning any books. which equation describes the number of books he has, y, after x weeks?
a. y = 5x
b. y = 5 - x
c. y = 1 + 5x
d. y = 5 + x

D. y = 5 + x

Step-by-step explanation:

At first Matt has 5 books, so initially the number of books 'y' is:

y = 5

And then every week he checked 1 book, so when 'x' number of weeks passed he checked (we multiply the number of books per week by the number of weeks 'x'):

1*x = x    number of books

this 'x' books are adiotional to the initial 5 books that he had.

So After x weeks he will still have the 5 initial books plus 'x' more books,

this gives us the equation that describes the total number of books:

y = 5 + x

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
