    2)which of the following function is equivalent to the following piece function.

    x-3, if x>=3
    3-x, if x<3

    a) g(x)=|x-3| b) g(x)=|x+3| c) g(x)=-|x-3| d)-|x+3| e) none of these

    Rearrange x + 2y = 6 to get x = 6 - 2y. Then plug this into x2 + y2 = 41. You get:

    (6 - 2y)2 + y2 - 41 = 0
