Thomas is cycling from the school to the playground. the equation shows thomas's distance (y), in miles, from the playground after x minutes.

y= 14 - 4x

what does the number fourteen represent?
options:
a) the speed at which thomas is cycling
b) thomas's distance from the playground when he begins cycling
c) thomas's distance from the school when he beings cycling
d) the rate of change of thomas's speed while cycling from school to the playground

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
