How do you solve a linear inequality and graph on a number line?

tiny-mole [99]

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:

<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>

Pls help ASAP! GIVING 100 POINTS FOR THE RIGHT ANSWERR!

marta [7]

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).
