Question

Is the inequality true. -2(2x+9)>_4x+9

Answer 1

Answer:

The inequality is not true

Step-by-step explanation:

we have

$-2(2x+9)> -4x+9$

Distributed left side

$-4x-18 > -4x+9$

Adds 4x both sides

$-18 > 9$ ----> is not true

Answer 2

Answer:  

The inequality is False

Step-by-step explanation:

We say that an inequality is true when the inequality symbol is satisfied. For example

$5> 2$   → True

On the contrary when inequality is not satisfied we say that it is false. For example:

$2> 30$  → False

2 is not greater than 30, therefore it is said that inequality is not satisfied.

In this case we have the following inequality:

$-2(2x+9)>-4x+9$

To find out if inequality is satisfied, we simplify the terms

$-2(2x+9)>-4x+9$

$-4x-18>-4x+9$

$-18>9$

Observe that -18 is not greater than 9, therefore it is said that inequality is not satisfied.
