3. a friend gives you two baseball cards for your birthday. afterward, you
begin collecting them. you buy the same number of cards once each
week. the equation y = 4x + 2 describes the number of cards, y, you
have after x weeks. (example 2)
a. find and interpret the slope and the y-intercept of the line that
represents this situation. graph y = 4x + 2. include axis labels.
b. discuss which points on the line do not make sense in this situation.
then plot three more points on the line that do make sense.

List the elements of the set in roster notation. (enter empty or ∅ for the empty set.) {x | x is a letter in the word hippopotamus}

Drag the tiles to the correct boxes to complete the pairs. match the cart-coordinates with their corresponding pairs of y-coordinates of the unit circle

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?
