Answer:

A) -2y + 2x >= 7x+y+5

Step-by-step explanation:

I can't remember how to get there by actually doing math, but I used a calculator on a program called Desmos (don't know if you've heard of it?). It's great because they have lots of types of calculators for any kind of math you're doing. I used the graphing calculator for this one. There's also a scientific calculator which I used a lot throughout middle school when we had to do operations with PEMDAS OR GEMS.

To find the graphing calculator for future problems like this, just type in Desmos Graphing Calculator and it should come up.

Hope you find it useful.

Find dy/dx by implicit differentiation. <br> 4x2 + 5xy - y2 = 6

Vlada [557]

4x^2 + 5xy - y^2 = 6
Implicitly differentiating both sides,
4(2x) + 5(x y' + y) - 2yy' = 0

where y' = dy/dx

8x + 5xy' +5y -2yy' = 0

combining y' terms
y' (5x-2y) +8x +5y = 0

y'(5x-2y) = -(8x+5y)

dy/dx = -(8x+5y)/(5x-2y)
or
dy/dx = (8x+5y)/(2y-5x)
