a. Describe the values of $(x)$ that make the sentence true.
b. Translate the sentence into an equation involving absolute value.

Short Answer

Expert verified

$x =11.6 and x =2.4$
$|x 鈭� 7| = 4.6$

Step by step solution

Part a. Step 1. Write down the given statement.

It is given that,

$x = 7 卤 4.6$

Part a. Step 2. Evaluate (x) from the given expression.

The values of x can be evaluated as:

$x =7卤4.6 x = (7 +4.6) and x = (7 - 4.6) x =11.6 and x =2.4$

Therefore, the values of x for which the given sentence is true are $x =11.6 and x =2.4$ .

Part a. Step 3. Conclusion from the obtained value of (x).

From the obtained values, the expression is true for $x =11.6 and x =2.4$ .

Part b. Step 1. Write down the given statement.

The given statement is:

$x = 7 卤 4.6$

Part b. Step 2. Evaluate (x) and determine mid-point from the obtained values of (x) by taking average.

The values of $x$ can be described as:

$x =7卤4.6 x = (7 +4.6) and x = (7 -4.6) x =11.6 and x =2.4$

First, we will find the average of the two given points, i.e. 2.4 and 11.6 to find the mid-point.

$= \frac{2.4 + 11.6}{2} = \frac{14}{2} = 7$

Part b. Step 3. Write the equation for the expression.

The distance from 2.4 to 7 is 4.6 units and the distance from 7 to 11.6 is also 4.6 units.

So, the equation will be $|x 鈭� 7| = 4.6$ .
