Answer:

$\frac{4}{15} + \frac{3}{5} - \frac{2}{3}$

$\frac{4 \times 1}{15 \times 1} + \frac{3 \times 3}{5 \times 3} - \frac{2 \times 5}{3 \times 5}$

$\frac{4}{15} + \frac{9}{15} - \frac{10}{15}$

$\frac{4 + 9 - 10}{15}$

$\frac{13 - 10}{15}$

$\frac{3}{15}$

$\frac{1}{5}$

hope it helps you :)

Find dy/dx if y =x^3+5x+2/x²-1

stiks02 [169]

<u>Differentiate using the Quotient Rule</u> –

$\qquad$ $\pink{\twoheadrightarrow \sf \dfrac{d}{dx} \bigg[\dfrac{f(x)}{g(x)} \bigg]= \dfrac{ g(x)\:\dfrac{d}{dx}\bigg[f(x)\bigg] -f(x)\dfrac{d}{dx}\:\bigg[g(x)\bigg]}{g(x)^2}}\\$

According to the given question, we have –

f(x) = x^3+5x+2
g(x) = x^2-1

Let's solve it!

$\qquad$ $\green{\twoheadrightarrow \bf \dfrac{d}{dx}\bigg[ \dfrac{x^3+5x+2 }{x^2-1}\bigg]} \\$

$\qquad$ $\twoheadrightarrow \sf \dfrac{(x^2-1) \dfrac{d}{dx}(x^3+5x+2) - ( x^3+5x+2) \dfrac{d}{dx}(x^2-1)}{(x^2-1)^2 }\\$

$\qquad$ $\twoheadrightarrow \sf \dfrac{(x^2-1)(3x^2+5) - ( x^3+5x+2) 2x}{(x^2-1)^2 }\\$

$\qquad$ $\pink{\sf \because \dfrac{d}{dx} x^n = nx^{n-1} }\\$

$\qquad$ $\twoheadrightarrow \sf \dfrac{3x^4+5x^2-3x^2-5-(2x^4+10x^2+4x)}{(x^2-1)^2 }\\$

$\qquad$ $\twoheadrightarrow \sf \dfrac{3x^4+5x^2-3x^2-5-2x^4-10x^2-4x}{(x^2-1)^2 }\\$

$\qquad$ $\green{\twoheadrightarrow \bf \dfrac{x^4-8x^2-4x-5}{(x^2-1)^2 }}\\$

$\qquad$ $\pink{\therefore \bf{\green{\underline{\underline{\dfrac{d}{dx} \dfrac{x^3+5x+2 }{x^2-1}} = \dfrac{x^4-8x^2-4x-5}{(x^2-1)^2 }}}}}\\\\$

Solve the following equations putting them in slope intercept form. Then

asambeis [7]

Answer:

1. slope is -1 and y intercept is 2

3. slope is -2 and y intercept is -4

2. slope is -4 and y intercept is 2

4. this is not a line - it is a parabola

Step-by-step explanation:

1. -4y = 4x -8

y = -x + 2

3. 4y = -8x -16

y = -2x - 4

2. y = -4x + 2

4. y - 14 = -3x^2 -16x

y = 3x^2 - 16x + 4
