PLS HELP ASAP NEED FOR A TEST

horrorfan [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x----> the first number

y----> the second number

we know that

$\frac{x}{y}=\frac{3}{4}$

$y=\frac{4}{3}x$ -----> equation A

$x+y=35$ ----> equation B

substitute equation A in equation B

$x+\frac{4}{3}x=35$

$\frac{3x+4x}{3}=35$

$\frac{7}{3}x=35$

$x=35*3/7=15$

$y=35-15=20$

Please help! x^3 +y^3=9

Crank

Step-by-step explanation:

Taking the derivative of both sides with respect to x, we get

$\dfrac{d}{dx}(x^3 + y^3) = \dfrac{d}{dx}(3)$

$\Rightarrow 3x^2 + 3y^2\dfrac{dy}{dx} = 0$

Solving for $\frac{dy}{dx}$ , we get

$\dfrac{dy}{dx} = -\dfrac{3x^2}{3y^2} = -\dfrac{x^2}{y^2}$
