Why is the product of two rational numbers always rational? select from the drop-down menus to correctly complete the proof. let a/b and c/d represent two rational numbers. this means a, b, c, and d and b and d are not 0. the product of the numbers is ac/bd, where bd is not 0. both ac and bd are and bd is not 0. because ac/bd is the ratio of the product is a rational number. all blanks are either: intergers or irrantional numbers

Let a/b and c/d represent two rational numbers. This means a, b, c, and d are__INTEGERS__, and b and d are not 0. The product of the numbers is ac/bd, where bd is not 0. Both ac and bd are _INTEGERS___, and bd is not 0. Because ac/bd is the ratio of two_INTEGERS, the product is a rational number.

i believe the answer to be 48

step-by-step explanation:

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
