A linear inequality is similar to a linear equation in that the largest exponent of a variable is 1. The following are examples of linear inequalities.
The methods used to solve linear inequalities are identical to those used to
solve linear equations. The only difference occurs when there is amultiplication or a division that involves a minus sign. For example, we know
that
$8>6$ . If both sides of the inequality are divided by
$-2$ ,
$-4$ is not
greater than
$-3$ . Therefore, the inequality must switch around, making
$-4<-3$ .
When you divide or multiply both sides of an inequality by any number with
a minus sign, the direction of the inequality changes. For this reason you cannot divide or multiply by a variable.
For example, if
$x<1$ , then
$-x>-1$ .
In order to compare an inequality to a normal equation, we shall solve an equation first. Solve
$2x+2=1$ .
If we represent this answer on a number line, we get
As you can see, for the equation, there is only a single value of
$x$ for which the equation is true. However, for the inequality, there is a range of values for which the inequality is true. This is the main difference between an equation and an inequality.

Is there any normative that regulates the use of silver nanoparticles?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
