How do I write an inequality for 6x+8>2

Hatshy [7]

Answer:

The inequality is $x>-1$

Step-by-step explanation:

Given:

The inequality to solve is given as:

$6x+8>2$

Now, in order to solve it for 'x', we need to isolate 'x' on one side of the inequality.

<em>Adding -8 on both sides, we get:</em>

$6x+8-8>2-8\\\\6x>-6$

<em>Dividing both sides by 6, we get:</em>

$\frac{6x}{6}>\frac{-6}{6}\\\\x>-1$

Therefore, the inequality for 'x' is given as:

$x>-1$

So, 'x' include all the values that are greater than -1.

What about this one ?

il63 [147K]

For this case we have the following equation:
x ^ 2 + 18x + 32 = 0
Rewriting we have:
x ^ 2 + 18x = -32
By completing squares we have:
x ^ 2 + 18x + (18/2) ^ 2 = -32 + (18/2) ^ 2
Rewriting:
x ^ 2 + 18x + (9) ^ 2 = -32 + (9) ^ 2
x ^ 2 + 18x + 81 = -32 + 81
x ^ 2 + 18x + 81 = 49
(x + 9) ^ 2 = 49
Answer:
(x + 9) ^ 2 = 49
