That depends on the numerical values of both 'x' and 'y'.

The expression "2x times y" represents the product of 2 times the variable x, and then multiplied by the variable y. In mathematical terms, this can be written as 2x * y or 2xy. This expression denotes the result of doubling the value of x and then multiplying it by y.
Well, darling, 2x times y is simply 2xy. It's not rocket science, honey, just a little multiplication. So, go ahead and multiply those two bad boys together and you'll have your answer.
y = -1/(3x7 + 2x - 9)y = -(3x7 + 2x - 9)-1y' = -(-1)(3x7 + 2x - 9)-2(3x7 + 2x - 9)'y' = (3x7 + 2x - 9)-2(21x6 + 2)y' = (21x6 + 2)/(3x7 + 2x - 9)2
y-2x=3 -y -y -2x=3-y -3 -3 -2x-3=-y /-1 /-1 2x+3=y y=2x and y=2x+3 have the same slope of 2, so they are parallel. Hope this helps! ;D

it means two times x times y.
2x / (y-2) + 2x / (2-y)First get a common denominator: (y-2) (2-y)Then you have:2x(2-y) / (y-2)(2-y) + 2x(y-2) / (y-2)(2-y), summing and simplifying, you get:(4x-4) / (y-2)(2-y)
