Solve the equation for the unknown variable.
Georgia [21]

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

A. y= 1/2x-14<br> B. y=1/2x-5<br> C. y=2x-14<br> D. y=2x-5
DanielleElmas [232]

Answer:

B. y=1/2x-5

Step-by-step explanation:

From the graph, we read the slope of line JK.

slope = rise/run = -3/-6 = 1/2

The equation we need has the same slope.

y = mx + b

y = (1/2)x + b

It passes through point P(6, -2). Now we find b.

-2 = (1/2)(6) + b

-2 = 3 + b

b = -5

The equation is

y = (1/2)x - 5
