Find an equation of the plane through the point (1, -5, 3) and perpendicular to the vector (2, -3, -3).

Steve earns $8 per hour his older brother earns $2 more per hour than steve what is the ratio of the money steve earns in an hour to the money of his brother earns in an hour.

Reflect the point (7,0) across the y-axis

1- 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.2- 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 the first question?
