What is the recursive rule for the sequence -3,-1, 1, 3...?
A f(1) = -3; f(n)=n+2
B f(1) = 3; f(n) = 2(n-1)
C (1)=-3; f(n)=f(n-1) + 2

Chose the graph below that represents the following system of inequality’s

Scale factor of 2 is used to enlarge a figure as shown below the area of is 18 in.²

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?
