Answer (1 of 15) Imagine y is an apple, so if you have two apples and add another apple, how much apples do you have now?

32(x+y)2-2x-2y- x y = 2 2 x 4 y = 32 x 5 y = 34 (We used 3 given that the third new equation is a linear combination of the first and second equation The third equation is the sum of the first and the second one) In the exercise, is equivalent to Because we divided the second equation by 2 (Notice that this is an example of 2 because weAnswer (1 of 8) The equation of a circle x^2 y^2 6x 2y 8 becomes x^2 y^2 6x 2y = 8 is of the form (xh)^2 (yk)^2 = r^2, or x^2 2hx h^2 y^2 2ky k^2 = r^2 Here 2hx = 6 or h = 3, and 2ky = 2y, or k = 1 h^2 k^2 = r^2 8, or 3^2 (1)^2 = r^2 8, or 9 1
