9. Darcy is buying apples and oranges for a large fruit basket to give away as a door prize at a charity event. Apples cost $0.24 each and oranges cost $0.80 each. She has $12 to spend and would like to
purchase at least 20 pieces of fruit in total.
a) Write a system of linear inequalities to represent
this situation, then graph.
b) Using your graph, give two possible combinations
of apples and oranges Darcy can buy.

Fredrick designed an experiment in which he spun a spinner 20 times and recorded the results of each spin

What expression is equivalent to (2x-1)(x-3)?

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?
