(\partial)/(\partial x)(9x+2y)

\frac{\partial}{\partial x} (9 x + 2 y)

9

Solution steps

\frac{\partial}{\partial x} (9 x + 2 y)

Treat

y

as a constant

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{\partial}{\partial x} (9 x) + \frac{\partial}{\partial x} (2 y)

\frac{\partial}{\partial x} (9 x) = 9

\frac{\partial}{\partial x} (2 y) = 0

= 9 + 0

Simplify

= 9

a re a y = 8 x - 12, y = x^{2}, x = 1

x \to 0 lim (\frac{tan ( x )}{2 x})
