Question

-3x^2y(xy^2-2y-1) .....With steps please :)

Answer 1

1min.

Answer 2

I agree (1) or (2) are INSUFFICIENT. but consider both of them together

(1) 2x-2y = 1
(2) x/y >1

Rephrasing (1)

x-y = 1/2
x = y + 1/2

Now substituting value of x in (2)

(y+1/2)/y >1

Solving:

1+ 1/2y > 1

so, 1/2y > 0 it means y >0 since x = y+1/2 s0 X >0 as well.

Hope it helps

Answer 3

That has nothing to do with the question she asked?

Answer 4

You need to use the distributive property to simplify this.

Take the term outside the parentheses and multiply it by each term inside.
