Y(1 10x2) = 1 10x2 y = x1 10 2 1 10x2 1 1 y = 10x2 1 10x2 1 It’s a good idea to check our work by plugging y = 10x 2 1 10x2 1 back into the original equation 3 2lny = ln(y 1) x Once again, we apply the inverse function ex to both sides We could use the identity e2lny = (elny)2 or we could handle the coe cient of 2 as shown below. Theorem 36 Let F be any partition of the set S Define a relation on S by x R y iff there is a set in F which contains both x and y Then R is an equivalence relation and the equivalence classes of R are the sets of F Pf Since F is a partition, for each x in S there is one (and only one) set of F.

If 3 jythen the equation y2 = x3 45 shows 3 divides x Write x= 3x 0 and y= 3y 0 , so 9y 02 = 27x 03 45, so y 02 = 3x 03 5, which implies y 02 2 mod 3, and that is impossible. So that's what this first equation gets turned into, if you put it in slopeintercept form y is equal to negative 3x plus 5 So if you were to graph it, the yintercept is 5 0, 5 And then its slope is negative 3 So you move 1 in the xdirection, you move down 3 in the ydirection Move 2, you would move down 6 2, 4, 6 Move 2, you go 2, 4, 6.
