Answer:

f(x) = \dfrac{3}{2}x

Step-by-step explanation:

The general direct variation equation is

y = kx

Plug in x = 4 and y = 6 and solve for k.

6 = k * 4

4k = 6

k = 6/4 = 3/2

f(x) = \dfrac{3}{2}x

The equation is false so no solution.

Simplify 8/5 * -6 to -48/5

Move the negative sign to the left

Simplify brackets

Since 48/5 = -54 its false so no answer

When homeowners list their home for sale, they begin by listing it for a price that is greater
Phantasy [73]

Answer:

-0.924

Step-by-step explanation:

The magnitude of the correlation coefficient is the square root of the variation.

|r| = √0.854

|r| = 0.924

The sign of the correlation coefficient is the same as the slope of the line of best fit.  In this case, it's negative.

r = -0.924

Answer:

1.  A point you can't move at all, a line you can only move back and forth in the same direction. Yes it is accurate for its characteristics because points and lines have no set definition for them

2. When you are on a point you can not travel at all in any direction while staying on that point. That means you have zero options to travel in. That is why it is said you have zero dimensions.

3. Normal space refers 3 dimensional space that extends beyond the three dimensions of length, width, and height.


4. If you can move backward, forwards, up and down in two different directions it is considered two dimensional. The two dimensional figure is considered a plane. For example, if you took a piece of paper that extended forever in every direction, that in a geometric a sense, is a plane. The piece of paper itself is itself, finite, and you could call the piece of paper a plane segment because it is a segment of an entire plane.
