Suppose that the polynomial x^2+y^2-1 is not irreducible.
It means that there exists two fractions such that :

We found that q divide t and q divide s, but s and t are supposed to be prime each other. It is a contradiction.
The polynomial x^2+y^2-1 is then irreducible in q[x,y]

Answer:
B
Step-by-step explanation:
The inequality is 1.20$ x + 3.60 < 9.60, the amount of money in total that Rammy has. As said, for each pound of peaches it would cost 1 dollar and 20 cents (1.20) So for the gallon of milk if Rammy bought it he would have 6$ left to spend on the pounds of peaches. So you do 6$ (600) divided by 1.20$ (120) and you would get 5 pounds of peaches. Therefore, Rammy can buy 5 or more pounds of peaches.
Answer:
3
Step-by-step explanation:
If you start at any point on the line, you can go up 3 points and go to the right by 1 point to get back to the line. This is where you get the number 3 because 3/1 is 3.
