This is very similar to solving linear equations except for one thing, If we multiply or divide by a negative number, we must flip the inequality sign.
<h3>What is linear inequality?</h3>
In mathematics, inequality occurs when a non-equal comparison is made between two mathematical expressions or two numbers. In general, inequalities can be either numerical inequality or algebraic inequality or a combination of both.
To better understand it, let's examine the example.
2x - 5 < 3
So, when we solve, let's just consider the inequality sign like a regular equal sign.
Let's start by adding 5 to each sides.
2x - 5 + 5 < 3 + 5
To find the value of x , we must divide it by two.
2x/2 <8/2
And the final result is x= 4.
This is our answer.
So if we need to graph it, let’s draw a number line and draw an open circle at 4. Open circle because x is not equal to 4. Then make an arrow going to the left.

Answer:
78.732
Step-by-step explanation:
Volume is length x width x height so
3.6 x 2.7 x 8.1 is 78.732
Answer:
<em>I think it didnt change</em>
Step-by-step explanation:
<em>Cause both areas from the line are the same and if it were to change the left would be diffrent from the right. So there i think it didnt change.</em>
Answer:
Cylinder
(with radius of 4 units and height of 4 units)
Step-by-step explanation:
First, determine the shape of the 2D figure.
Point B is above point A, and point C is above point D.
Point A and B, and points C and D are on the same horizontal line.
Points A and B both have an x-value of zero.
Points C and D both have an x-value of 4.
Therefore, the width of the shape is 4 units
Points A and D have an y-value of zero.
Points B and C have an y-values of 4.
Therefore, the height of the shape is 4 units.
Therefore, the shape of the 2d figure is a square with side length of 4 unit. (See first attached image).
If the square is rotated above the y-axis, it creates a cylinder with a radius of 4 units and a height of 4 units. (See second attached image).
