${x}^{2} + 2x = 24 \\ {x}^{2} + 2x - 24 = 0 \\ {x}^{2} + (6x - 4x) - 24 = 0 \\ ({x}^{2} + 6x) - (4x + 24) = 0 \\ x(x + 6) - 4(x + 6) = 0 \\ (x - 4)(x + 6) =0 \\ \\ therefore \: \: the \: values \: of \: x \: are \: 4 \: and \: - 6.$

Find the value of 'y' in the equation 3/y-3 =8

ElenaW [278]

3 / (y - 2) = 8....multiply both sides by (y - 2), eliminating it on the left side

3 = 8(y - 2)
3 = 8y - 16
3 + 16 = 8y
19 = 8y
19/8 = y
2 3/8 = y <==

Find the value of the derivative (if it exists) at the indicated extremum. (If an answer does not exist, enter DNE.)

Answer:

The answer is "0".

Step-by-step explanation:

Please find the correct question in the attached file.

Given value:

$\to f(x) =\frac{x^2}{x^2+5}\\\\$

Formula:

$\bold{\frac{d}{dx} \frac{u}{v} = \frac{ v \frac{du}{dx} - u \frac{dv}{dx}}{v^2}}$

$\to f'(x) =\frac{(x^2+5) 2x -2x^3 (2x)}{(x^2+5)^2}\\\\\to f'(0) =\frac{(0^2+5)2(0) -4(0)^4}{(0^2+5)^2}\\\\\to f'(0) =\frac{(0)(5) -2(0)}{(5)^2}\\\\\to f'(0) =\frac{0 - 0}{(5)^2}\\\\\to f'(0) =\frac{0}{25}\\\\\to f'(0) = 0$
