8. (09.04 LC) A circle is centered at (-4,-6) and has a radius of 3. Which of the following is the equation for this circle? (6 points)
(x + 4)2 + (y + 6)2 = 3
O (x - 4)2 + (y - 6)2 = 9
O (x-4)² + (y - 6)² = 3
(x + 4)2 + (y + 6)2 = 9

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?

2x minus y equals 6, x plus y equals negative 3

Pls what is the relative minimum of the function? enter your answer in the box
