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

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

Solve y = f(x) = (2x+1)^1/2 & g(x) = x-1

snow_lady [41]

Answer:

f(x) = $x = \frac{y^{2} - 1}{2}$

g(x) = 1

Step-by-step explanation:

y = (2x + 1)^1/2

$y^{2} = 2x + 1$

$y^{2} - 1 = 2x$

$\frac{y^{2} - 1}{2} = x$

y = x - 1

y + 1 = x

The answer is -128
-16(6)² + 32(6) + 384 = 0
-16(4)² + 32(4) + 384 = 256
0 - 256/6 - 4 = -128

4−6n=60−2n what is n?

Nadusha1986 [10]

Answer:

n = -14

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

4 - 6n = 60 - 2n

Step 2: Solve for n

Add 6n to both sides: 4 = 60 + 4n
Subtract 60 on both sides: -56 = 4n
Divide both sides by 4: -14 = n
Rewrite: n = -14

Step 3: Check

Plug in n into the original equation to verify it is a solution.

Substitute in n: 4 - 6(-14) = 60 - 2(-14)
Multiply: 4 + 84 = 60 + 28
Add: 88 = 88

Here we see that 88 does indeed equal 88.

∴ n = -14 is a solution of the equation.
