Graph the solution to this inequality on the number line.

[tex]\[ 0.3(x - 4) \ \textgreater \ -0.3 \][/tex]


Sagot :

Certainly! Let's solve and graph the inequality [tex]\( 0.3(x-4) > -0.3 \)[/tex] on the number line.

### Step-by-Step Solution:

1. Start with the given inequality:
[tex]\[ 0.3(x-4) > -0.3 \][/tex]

2. Eliminate the coefficient of [tex]\( (x-4) \)[/tex] by dividing both sides by 0.3:
[tex]\[ \frac{0.3(x-4)}{0.3} > \frac{-0.3}{0.3} \][/tex]
Simplifying both sides gives:
[tex]\[ x - 4 > -1 \][/tex]

3. Isolate [tex]\( x \)[/tex] by adding 4 to both sides of the inequality:
[tex]\[ x - 4 + 4 > -1 + 4 \][/tex]
Simplifying this, we get:
[tex]\[ x > 3 \][/tex]

### Graphing on the Number Line:

To represent [tex]\( x > 3 \)[/tex] on the number line, follow these steps:

1. Draw a horizontal line and mark a point labeled 3 on it.
2. Since [tex]\( x \)[/tex] must be greater than 3, you’ll draw an open circle at 3 to indicate that 3 is not included in the solution.
3. Draw a ray starting from 3 and extending to the right, indicating all the numbers greater than 3.

Here is the number line representation of the inequality [tex]\( x > 3 \)[/tex]:

```
-∞ | 0 | 1 | 2 | 3 | 4 | 5 | ∞
------------------------------------------------------------------------>
o-------->
3
```
In this graph:
- The open circle at 3 indicates that 3 is not included.
- The arrow pointing to the right indicates that all numbers greater than 3 are included in the solution.

Therefore, [tex]\( x > 3 \)[/tex] is graphically represented on the number line as shown above.
