Answer:

Inequalities work exactly like equations with one exception. The process begins just like equations: first, do the opposite of what you see, then do the same thing on the other side of the sign. At the last step of solving an inequality, if you multiply or divide by a negative number, then you reverse the sign

The two examples show the process of solving inequality with variables on both sides are

3 + x > 3x - 6

3 - 4x < 2x + 8

The process is shown below.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

Let us consider an inequality:

3 + x > 3x - 6 ____(1)
3 - 4x < 2x + 8 _____(2)

We will solve for x.

From (1),

3 + x > 3x - 6

Subtract 3 on both sides.

3 + x - 3 > 3x - 6 - 3

x > 3x - 9

Add 9 on both sides.

x + 9 > 3x - 9 + 9

x + 9 > 3x

Subtract x on both sides.

x + 9 - x > 3x - x

9 > 2x

Divide 2 on both sides.

9/2 > x

x < 9/2

This means that x must be less than 9/2.

From (2),

3 - 4x < 2x + 8

Subtract 3 on both sides.

3 - 4x - 3 < 2x + 8 - 3

- 4x < 2x + 5

Subtract -2x on both sides.

-4x - 2x < 2x + 5 - 2x

-6x < 5

Divide both sides by 6.

-x < 5/6

Since we can not keep a negative sign with x we will multiply a negative on both sides and flip the inequality.

- (-x) > -5/6

x > -5/6

Thus,

The two examples show the process of solving inequality with variables on both sides are:

3 + x > 3x - 6

= x < 9/2

3 - 4x < 2x + 8

= x > -5/6

Answer:

negative one half D

Step-by-step explanation:

Multiply - two thirds x six eightths 6x2=12 you can multiply straight acroos because it is multiplycation. Now you do 8x3= 24 half of 12 is 24 so 12 over 24    simplifying is just dividing.  but if you look closer their is a negative sign so  what ever fraction is biger you go with their sign so your offical awnser  is negative one half

Answer:

[tex]\displaystyle y=8x[/tex]

Step-by-step explanation:

We are given a table and we want to determine a linear equation (in slope-intercept form) that represents this table.

So, we will first need to determine the slope. We can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are two points.

We have three points: (1, 8), (2, 16), and (3, 24).

Let’s pick two. We can use (1, 8) and (2, 16).

So, let (1, 8) be (x₁, y₁) and let (2, 16) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{16-8}{2-1}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{8}{1}=8[/tex]

So, our slope is 8.

Now, we can determine the equation using point-slope form:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

Where m is our slope and (x₁, y₁) is a point.

We know that the slope is 8, so we will substitute 8 for m.

We can use any of our three points for the point. Let’s use (1, 8) for consistency. So, let (1, 8) be (x₁, y₁). Substitute appropriately:

[tex]\displaystyle y-8=8(x-1)[/tex]

Solve for y. Distribute the right:

[tex]\displaystyle y-8=8x-8[/tex]

Add 8 to both sides:

[tex]\displaystyle y=8x[/tex]

And we have our equation.

Notice that this is a direct variation or proportional equation as we don’t have a y-intercept.

Answer:

The diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm

The radius will be 15.9134 ÷2 = 7.9567 cm or about 7.96 cm

The area of a circle is given by \pi × square of radius

Area = 3.142 × 7.96×7.96 = 199.0821 square cm

Answer:

the diameter would be half of the original length because it needs to be a circle so each half of the circle would equal 25 centimeters
