Suppose we want to choose 5 objects, without replacement, from 13 distinct objects. (a) How many ways can this be done, if the order of the choices is taken into consideration?

(b) How many ways can this be done, if the order of the choices is not taken into consideration?

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

your answer would be 12
