9. DETAILS Implicit Differentiation. The demand equation for a certain brand of two-way headphones is 3x3-7xy + 3y2 = 5 where x represents the number (in thousands) of headphones demanded each week when the unit price is y. Find by implicit differentiation for the given equation. dx O dy -9x2 dx -7x + 6y O none of the other answers O dy -9x2 dx -7+ 6y O dy -(9x2-7y) dx -7x + 6y O dy 9x2-7y dx -7x + 6y
