Algebra 1A Unit 6 lesson 9 portfolio (Brainliest to correct answer) Task 3
cabs use commodity- gas! Research average gas prices from 2005-2015 for the city you chose. If you cant find this information for your specific city, you can research national gas price averages instead. a. Create a table showing the average gas price each year. b. Create a scatter plot of the data in your table(remember to label your axes.)

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?
