GCF(18xy, 15xy) = 3xy LCM(18xy, 15xy) = 90xy
the GCF is 6y
x,y,1,2,3,6,9,18 are the factors of 18xy....
18xy is the GCF of 72x2y and 18xy
The GCF is 6xy. The LCM is 72xy2
The GCF is 13x
We are missing an important sign (+/-) I shall assume 9x2 - 18xy + 9y2 9(x-y)(x-y)
lcm(8x, 18xy) = 72xy 8x = 23 x x 18xy = 2 x 32 x x x y lcm = 23 x 32 x x x y= 72xy
63
GCF = 9To find the LCM, find the prime factorization of each number9y = 3 * 3 * y18x = 2 * 3 * 3 * xLCM = 2 * 3 * 3 * x * y = 18xy
That equation represents only one line. y - 11 = 13x - 7 y = 13x + 4 The slope is 13.
That equation represents only one line. y - 11 = -13x - 7 y = -13x + 4 The slope is -13.
