Step-by-step explanation:
Given: ![y = -\dfrac{2}{x}](https://tex.z-dn.net/?f=y%20%3D%20-%5Cdfrac%7B2%7D%7Bx%7D)
Derivative of a power function
:
![\dfrac{d}{dx}(x^n) = nx^{n-1}](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7Bdx%7D%28x%5En%29%20%3D%20nx%5E%7Bn-1%7D)
Therefore,
![\dfrac{dy}{dx}=-2(-1)x^{-2} = \dfrac{2}{x^2}](https://tex.z-dn.net/?f=%5Cdfrac%7Bdy%7D%7Bdx%7D%3D-2%28-1%29x%5E%7B-2%7D%20%3D%20%5Cdfrac%7B2%7D%7Bx%5E2%7D)

Answer:
7 1/7
Step-by-step explanation:
For the problem:
5
/7
× 10 = ?
Convert any mixed numbers to fractions:
10 = 10
Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:
5 × 10
7 × 1
=
50
/7
50 ÷ 7 = 7R1, therefore:
50
/7
= 7 1/7
The result is:
5
7
× 10 = 7 1/7
