Answer:

d = -3

Step-by-step explanation:

Given the equation:

d^3 = -27

Solve for d:

Take both sides cube root we have;

d =\sqrt[3]{-27}

We can write 27 as:

27 = 3 \cdot 3 \cdot 3 = 3^3

then;

d = \sqrt[3]{-3^3}

Using the rules:

\sqrt[n]{a^n} = a

\sqrt[3]{-1} = -1

then;

d = -\sqrt[3]{3^3} = -3

therefore, the unknown variable d is, -3

Alex_Xolod [135]
I'm assuming the the numbers coming after the variables are meant to be exponents, and if I'm wrong just let me know

-3x^4 - 2x^3 + 3x^2 + 3x^4 - 4x^3 + x^2, rearrange to have like terms in order
-3x^4 +3x^4 - 2x^3 - 4x^3 +3x^2 + x^2, now simplify
                0    -6x^3 + 4x^2

Find the inverse g(x)=x/5-6
STALIN [3.7K]
Interpreted: g(x) = \frac{x}{5} - 6
Let y = g(x)
y = \frac{x}{5} - 6
x = \frac{y}{5} - 6 (Interchange the x and y-values)

\frac{y}{5} = x + 6 (Solve for y)
y = 5(x + 6)

\therefore g^{-1}(x) = 5(x + 6)
