Property of equality

The property of the equality is a method to perform a operation both sides of the equal sign which will not affect the equation.

Inverse means to revere something which has been done earlier. An undo operation in mathematics is the operation of undoes what was done by the previous operation.

For example suppose the given expression is no 5. Then by adding 4 and again subtracting 4 keeps the system isolate.

Hence the property of equality which is needed to isolate a variable and solve a given equation is use inverse relationships to "undo" the operation. Thus the option A is the correct option.

Answer: Yes

Step-by-step explanation:

Because a=b, we can use the Substitution Property of Equality to substitute a for b. Now our equation looks like this:

a+a=a+a

Using the Reflexive Property, we know that this equation is true. We can use an example by setting a=2. This is what that would look like:

a=2

a=b          transitive property

b=2

a+a=a+b  substitution property

2+2=2+2

4=4          true

Therefore, yes, it is possible for a+a=a+b when a=b

Shapes that are symmetrical (or symmetric) have an identical side on each side. A symmetry may be divided into four primary categories: translation, rotation, reflection, and glide reflection.

Shapes that are symmetrical (or symmetric) have an identical side on each side. When mirrored, rotated, or translated, symmetrical forms retain their original appearance. A symmetry may be divided into four primary categories: translation, rotation, reflection, and glide reflection. The line dividing an animal into two halves is referred to as symmetry. Asymmetry, radial symmetry, and bilateral symmetry are only a few examples of symmetry. Animals are classified according to these symmetries, which are distinct from one another. Rotational symmetry, reflection symmetry, translation symmetry, and glide reflection symmetry are some examples of symmetries. Planar symmetry, which refers to various forms of symmetry on a flat surface, is shown by these four different types of symmetry.

The operations being done in each step are:

(1) Use the distributive property

(2) Subtraction property of equality.

(3) Addition property of equality.

(4) Division property of equality.

Two or more expressions with an equal sign are defined as an equation.

3(-3x-4) = 5x+2

Use distributive property:

-9x -12 = 5x + 2

Subtract 5x from both sides of the equation:

-14x -12 = 2

Add 12 to both sides of the equation:

-14x = 14

Divide both sides by -14:

x = -1

Hence, the operations being done in each step are:

The line m passing through the points (2, -7) and (4, -9) is parallel to the line y = -x + 2 , the correct option is (c) .

In the question ,

it is given that ,

the Line m passes through the points (2,-7) and (4,-9),

So , the slope of the line will be = (-9 + 7)/(4 - 2)

= -2/2

= -1

We know that the if two lines are parallel then they will have same slope ,

the slope of the line should be -1,

from the given options , we can see that only option (c) has the slope = -1

on comparing equation y = -x + 2 with the general equation of the line y = mx + c , we get

slope(m) = -1

hence , the line m is parallel to y = -x + 2 .

Therefore , the line m passing through the points (2, -7) and (4, -9) is parallel to the line y = -x + 2 .

The given question is incomplete , the complete question is

Answer: The percentage of a cereal box would be 1/3 or 33.33%.

Step-by-step explanation:

The value of x in the given equation, 2^(3x+1)=1/4, is x = -1

From the question, we are to solve the given given equation.

The given equation is

2^(3x+1) = 1/4

To solve the equation, we will determine the value of x.

Solving for x in the equation

2^(3x+1) = 1/4

Express 1/4 in index form

NOTE: 1/4 = 4^-1 = 2^-2

Thus,

The equation becomes

2^(3x+1) = 2^-2

Now, equate the powers

That is,

(3x + 1) = -2

3x + 1 = -2

Subtract 1 from both sides of the equation

3x + 1 - 1 = -2 - 1

3x = -3

Divide both sides of the equation by 3

3x/3 = -3/3

x = -1

Hence, the solution is x = -1

What is Arithmetic Progression?

An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"

The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁

Sum of first n terms of an AP : Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]

Sum of first n terms of an AP : Sₙ = ( n/2) ( a+b )

where a = first term

b = last term

Given data ,

First term a = 3

Number of terms n = 12

Sum of n terms Sₙ = 612

Let the last term of the AP be = b

Sum of first n terms of an AP : Sₙ = ( n/2) ( a+b )

Substitute the values of a , Sₙ and n in the equation

612 = ( 12/2 ) ( 3 + b)

612 = 6 ( 3 + b )

Divide by 6 on both sides , we get

102 = 3 + b

Subtract 3 on both sides , we get

b = 99

Hence , the last term of the Arithmetic Progression is 99

Number of boys in the class = 15 boys

Number of girls in the class = 20 girls

The ratio can be defined as the a number that can be used to express one quantity as a fraction of the other ones. That means we are comparing them by dividing those numbers

Here the ratio will be

Number of boys in the class : Number of girls in the class

Substitute the values in the ratio

= 15 : 20

Divide both numbers by 5

A line that intersects two or more lines at a distinct point is known as a transversal line.

A transversal is a line in geometry that connects two lines in the same plane at two different places. When determining whether two or more other lines in the Euclidean plane are parallel, transversals are important. Consecutive interior angles, consecutive exterior angles, corresponding angles, and alternate angles are only a few examples of the several pairings of angles that can be formed when a transversal intersects two lines. Euclid’s parallel postulate states that if two lines are parallel, then comparable interior angles are equal, alternate interior angles are equal, and successive interior angles are supplementary.

From the question, we have the following equation that can be used in our computation:

f(x) = (3/4)^x

This equation can be re-expressed as

f(x) = (3/4)ˣ

The x values on the table of values are given as: x = -2, -1, 0, 1 and 2

The next step is to substitute these values

So, we have the following equations

f(-2) = (3/4)⁻² = 16/9

f(-1) = (3/4)⁻¹ = 4/3

f(0) = (3/4)⁰ = 1

f(1) = (3/4)¹ = 3/4

f(2) = (3/4)² = 9/16

When these equations are represented on a table of values, we have the following table:

x  -2       -1      0     1      2

y  16/9   4/3   1     3/4   9/16

Next, we represent the values on a graph

From the table, we have

y = 1 when x = 0

This means that it crosses the y-axis at (0, 1)

This is represented by graph (a)
