Answer 2

The following are the answers.

a = Commutative property of multiplication.

b = Identity property of multiplication.

c = Associative property of multiplication.

d = Inverse property of addition.

e = Identity property of multiplication.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

x ⋅ 4 y = 4 x ⋅ y

This is the commutative property of multiplication.

a . b = b . a

100 ⋅ 1 = 100

This is the identity property of multiplication.

a . 1 = a

x (3 ⋅ 2x) = (x ⋅ 3) ⋅ 2x

This is the associative property of multiplication.

(a x b) x c = a x (b x c)

3+(−3)=0

This is the inverse property of addition.

−8 . (1/−8) = 1

This is the identity property of multiplication.

Thus,

The following are the answers.

a = Commutative property of multiplication.

b = Identity property of multiplication.

c = Associative property of multiplication.

d = Inverse property of addition.

e = Identity property of multiplication.

A 50-centimeter piece of wire is bent into a circle. What is the diameter of the circle? What is the radius of the circle? What is the area of the circle?

Answers

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

hi okay so if the original coords are a=(-2,0) b=(-3,-2) and c=(-5,-2), if one of the coords on the dilated triangle are (7,3), you apply that to the rest. so i think a=(7,3) b=(10.5,7) c=(17.5,7)but i’m not sure cause it says the constant is 4 but if you apply the constant of (7,3), the constant is -3.5. if you apple the constant of 4, the answers don’t really make sense.

answer: a=(7,3) b=(10.5,7) c=(17.5,7) i think

this question actually doesn’t really make sense at all. but i hope this helps lol.

I think you have to add your coordinates together which would probably give you 7.3 I’m sorry if this is not the answer

Answers

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:I believe its y=8x or y=8

Explain the process of solving inequality with variables on both sides. Show an example.

Answers

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.

What is inequality?

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
