Tom is trying to write 3/47 as a decimals. He used long division and divided until he got the quotient 0.0638297872, at which point he stopped. Since the decimals doesn't seem to terminate or repeat, he concluded that 3/47 is a not a rational number. Do you agree or disagree? Why?

add 8+12 to get a simplified answer of 12r-20

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
