Roberto said I'm thinking what is a fraction equivalent to 3/9 with a denominator 2 more than the numerator of a fraction that is equivalent to 3/9 the denominator is two more than the numerator what fraction is Roberto thinking of

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be

5x10^11 x 65

325 x 10^11

or

325,
