It is: 7a/5xy
5xy+4=9 is the problem, right? 5xy+4=9. Now subtract the 4 from both sides. 5xy=5. Ok, then, that looks less scary. Now, divide both sides by 5, to get xy=1. Hmm, a lot simpler. Now, divide both sides by x to get y by itself. So, y=1/x. Alright. That's your line! No, its not a straight line. There is a vertical asymptote where x=0, and the two segments aren't straight. But that's a simpler form of the equation. Hope that helped!
To find the derivative of the expression (5xy) with respect to (x), we can use the product rule. The derivative is given by ( \frac{d}{dx}(5xy) = 5 \left( x \frac{dy}{dx} + y \right) ). Thus, the derivative of (5xy) is (5y + 5x \frac{dy}{dx}).

You need at least two terms to find a GCF.

x2 + 5xy - 18y2 can not be factored.
What is : 5xy- x2t + 2xy + 3x2t
In the given expression you replace x by 2 and y by 1. Thus 5xy + 7x2 - 12y = 5*x*y + 7*x2 - 12*y = 5*2*1 + 7*22 - 12*1 = 10 + 28 - 12 = 26
To find the derivative of the expression (5xy) with respect to (x), we can use the product rule. The derivative is given by ( \frac{d}{dx}(5xy) = 5 \left( x \frac{dy}{dx} + y \right) ). Thus, the derivative of (5xy) is (5y + 5x \frac{dy}{dx}).
