Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)

factor out a 3x 3x(x-3)=3x2-9x
Since 3x is a factor of 3x^2, it is automatically the GCF.
3x - 2y and 3x + 2y are in their simplest form. They don't factor.
(3x - 7y)(2x + 9y)
If that's -18y2, the answer is (3x - 2y)(x + 9y)
-3x+9y = 6 9y = 3x+6 y = 1/3x+2/3
3x-9y-27
If you mean: -3x+9y = -6 then it is y = 1/3x-2/3
3x - 9y = 27-9y = -3x + 279y = 3x - 27y = x/3 - 3The graph is a straight line, with (slope = 3), and passing through the point (y = - 3) on the y-axis.
A linear equation in the form y = mx + c has slope m Any line parallel to 3x + 9y = 5 has the same slope 3x + 9y = 5 → 9y = -3x + 5 → y = (-3/9)x + 5/9 → y = -⅓x + 5/9 → Every line parallel to 3x + 9y = 5 has slope -⅓.
3x-2y+9+9y-x = 2x+7y+9
9y-81=9*(y-9)
Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
4x2 - 9y Not factorable from what I see.
