The equation y = 3.50x + 5 represents the number of dollars, y, Kristin charges for driving you x miles in her taxi. Determine if there is a constant of variation. If yes, then type the constant of variation (numerical value). If no, then type none. help!!

You purchased 8 pounds 10 ounces of candy from a candy shop. you want to split it equally among 3 classrooms at a local school.

Each equation given below describes a parabola. which statement best compares their graphs? x = 2y^2 x = 8y^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?
