Answer:

D. 7

Step-by-step explanation:

(8+4) = 2(x-1) multiply (x-1) by 2

(8+4) = 2x-2 add 8 and 4

12 = 2x-2 add 2 on both sides

14 = 2x divide both sides by 2

7 = x

Find the second derivative y=1/5x^2+1/11x

Amiraneli [1.4K]

$\frac{dy}{dx}=\frac{1}{5}.x^{2-1}.2 + \frac{1}{11}.x^{1-1}.1$

$\frac{dy}{dx}=\frac{2}{5}.x+\frac{1}{11}$

$\frac{d^2y}{dx^2}=\frac{2}{5}.x^{1-1}.1$

$\frac{d^2y}{dx^2}=\frac{2}{5}$
