Deandre's uncle from Japan promised to give him 21 g of gold. The local jewelry exchange will buy gold for $1152 per ounce. How much money can Deandre get for selling the gold? Use 1 oz = 28 g and do not round any computations.

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)

Give me the equations of two lines that have the same slope but are not parallel.

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?
