BOI ITS 19 LOL or is it 21?!
Answer: a.
Step-by-step explanation:
You have to complete the squares on both the x terms and the y terms in order to solve this. Move the 20 over to the other side so it's negative. Group the x terms together and complete the square to get (x^2+2x+1) and then do the same with the y terms: (y^2-4y+4). You have to add 1 and 4 to other side with the 20 to get a 25. Then create 2 perfect square binomials within each x and y value to get the vertex coordinates: (x+1)^2 + (y-2)^2 = 25. This tells us that the vertex is located at (-1, 2) and the radius is the square root of 25 which is 5.So the answer is the first choice above.
Yes it is possible,t<span>hey never intersect, so there is </span>no<span> point that lies on both lines, and </span>no solution<span> to the </span><span>system</span>
Answer: -4x+2y=12
Step-by-step explanation:All you have to do is multiply the variables one after the other taking note of the sign
