If mr. khan buys 15 staplers, it would cost him $254.85. how would you write this using function notation?

First you would need to find the price of each individual stapler which would be found by dividing the total price by the amount of staplers bought. This would be expressed by 254.85/15 which equals 16.99. This means each individual stapler costs 16.99. The slope intercept form is y=mx+b and since there is no additional pricing other than the staplers, it would just be 16.99 times the amount of staplers bought. Thus...

The answer to your question would be 254.85 = 16.99(15) or y = 16.99(x).

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
