Does the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the tabl
lukranit [14]

Answer:

- Inverse Variation

- Equation: XY = 12

Step-by-step explanation:

Given

X-> 2 | 4 | 8 | 12

Y-> 6 | 3 | 3/2 | 1

Required

- State the type of variation the table represents

- Determine the equation to model the data

To check for type of variation; we'll make use of trial by error method.

To start with; We'll check for direct variation.

This is done using the following expression;

Y = kXwhere k is the constant of variation

Make k the subject of formula

k = \frac{Y}{X}

When Y = 6, X= 2

K = \frac{6}{2} = 3

When Y = 3, X = 4

K = \frac{3}{4}

There's no need to check further as both values of k are not equal

To check for inverse variation;

Y = \frac{k}{X}

Make k the subject of formula

k = YX

When Y = 6, X= 2

K = 6 * 2 = 12

When Y = 3, X = 4

K = 3 * 4 = 12

When Y = 3/2; X = 8

K = \frac{3}{2} * 8 = \frac{24}{2} = 12

When Y = 1, X = 12

K = !2 * 1 = 12

Note that for all values of X and Y, K remains constant;

Hence, the table represents an inverse direction

To determine the equation;

We make use of  k = YX

Substitute 12 for k

So, the equation becomes

12 = XY

Reorder

XY = 12

Hence, the equation is XY = 12

2(1 – x) &gt; 2x HELP ASAP!!! I CANT FIGURE THIS OUT
katrin [286]
<h3>Answer:  x < 1/2</h3>

This is the same as saying x < 0.5 since 1/2 = 0.5

====================================================

Work Shown:

2(1-x) > 2x

2*1 + 2*(-x) > 2x ..... distribute

2 - 2x > 2x

2 > 2x+2x .... adding 2x to both sides

2 > 4x

4x < 2 ..... flip both sides; flip the inequality sign

x < 2/4 ..... dividing both sides by 4; see note below

x < 1/2

Note: We do not flip the inequality sign here because we are dividing both sides by a positive value. The inequality sign would only flip if you divide both sides by a negative number.
