No.No.No.No.
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}).

5xy+4=9
No.No.No.No.
(-5xy):(-xy)=
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
You need at least two terms to find a GCF.
It is: 7a/5xy
It is 5xy + 5x.
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.

x2 + 5xy - 18y2 can not be factored.
You cannot have xy= anything. Only x can be there at the end. x=5y=5 Divide 5y for all 3 sides to get 5xy=y Then divide y from both sides to get 5x=1 Therefore, x=1/5
What is : 5xy- x2t + 2xy + 3x2t
