Edit:
i just realized i answered the wrong question

The correct response is [C]: If and only if the angles are nearby, two angles form [a] linear pair.

Think about the response option shown in "Answer choice: [C]":

If and only if the angles are contiguous, two angles constitute a linear pair.

Then, think about the next:

1) "Two additional angles make a linear pair."

Is this a fact? Of course, but not always. (In other words, "sometimes") By definition, a "linear pair" of angles IS supplementary, but not all supplementary pairs of angles are linear pairs. In order for supplementary angles to also be "linear angles," they MUST ALSO BE ADJACENT.

2) "Two vertical angles are next to each other." Is this a fact? It's not true; it never is.

In light of the fact that this biconditional is NOT an acceptable definition, answer choice "C" is the one that is appropriate. This can be determined by looking at all the other options.

Think about the other response options:

The maxim "Two angles are supplementary if and only if the total of their angles measures 180" is the correct response.

is WRONG despite being a nice definition:

1) The total of the measurements of two additional angles is 180 degrees.

2) Two angles are supplementary if the total of their measurements equals 180 degrees.

"Two angles are vertical angles only if they are not close to one other and are produced by two intersecting lines," is the correct response (option B);

is WRONG despite being a nice definition:

1) Nonadjacent angles are those created by two crossing lines when two angles are vertical.

2) Two angles are vertical angles if they are nonadjacent angles created by two intersecting lines.

The sum of two angles equals 90 if and only if both angles are complementary (answer option [D]);

is WRONG despite being a nice definition:

1) The total of two complimentary angles' measurements equals 90 degrees.

2) Two angles are complimentary if the total of their [measured] is 90 degrees.

The simplification of the logarithmic expressions log₇7 is 1.

Logarithmic terms represent numbers in logarithmic form. It's also known as a log term.

A quantity can also be defined as the sum of two or much more quantities. As a result, a term may be the product of 2 different or more quantities, one of which must be in log form. Log terms are used in such cases.

A quantity can also be defined as the product of two quantities. As a result, if a term includes a quotient of amount, and at least a single quantities could be articulated in log form, the conditions are referred to mathematically as log terms.

Now, as the e=question stated;

Which graph correctly shows the system of equations [tex]\left \{ {{x-2y=4} \atop {y=2x+4}} \right.[/tex] ?

Correct graph for the system of equations is 3rd graph.

We graph the collection of ordered pairs that make up the equation's solution when graphing a system of equations in two variables.

The universal equation for any straight line is y=mx+c. m is the line's slope, and c is the y-intercept.

First, we take the equations as x-2y=4 as equation (1) and y=2x+4 as equation (2).

Now solve the equation (1)

x-2y=4

The equation is not in the form of y=mx+c.

So, we write as y= [tex]\frac{1}{2}[/tex]x-2

Here, slope m=[tex]\frac{1}{2}[/tex] and y-intercept is (0,-2).

If we take x=2 we get y=-1.

y= [tex]\frac{1}{2}[/tex](2)-2

y=1-2

y=-1

Now we have 2 solution for the equation (1) that are (0,-2) and (2,-1).

If we see the third graph in the given options.

There is a blue straight line and that is the line for equation (1) there we can see the points (0,-2) and (2,-1).

Now solve the equation (2)

y=2x+4

The equation is in the form of y=mx+c.

Here, slope m=2 and y-intercept is (0,4).

If we take x=1 we get y=6.

y= 2(1)+4

y=2+4

y=6

Now we have 2 solution for the equation (2) that are (0,4) and (1,6).

If we see the third graph in the given options.

There is a green straight line and that is the line for equation (2) there we can see the points (0,4) and (1,6).

Therefore, the correct graph for the given system of the equation[tex]\left \{ {{x-2y=4} \atop {y=2x+4}} \right.[/tex] is the third graph.

The product using the distributive property is 12z+8y²-8x+16 in the standard form.

The distributive law, which states that a × (b + c)=(a × b)+(a × c), is generalized by the distributive property of binary operations.

In every scenario, the distributive property can be summed up as follows:

Each summand (or minuend and subtrahend) is multiplied by this factor, and the resulting products are added, to multiply a sum (or difference) by a factor (or subtracted).

This concept states that multiplying the sum of two addends by a number will produce the same outcome as multiplying each addend separately by the number and then adding the results.

Given product: 4×(3z+5+2y²-2x-1)

Using the distributive property we can write it as:

= (4×3z)+(4×5)+(4×2y²)-(4×2x)-(4×1)

= 12z+20+8y²-8x-4

= 12z+8y²-8x+16

The total cost of the book including the sales tax is $10.85.

For the given question;

The original price of the book is $9.95.

The sales tax rate is 9%.

Then, 9% of 9.95 is;

= (9×9.95)/100

= 0.8955

The total cost will become;

Selling cost = original cost + sales cost

Selling cost = 9.95 + 0.8955

Selling cost = 10.84555

or rounding off.

Selling cost = $10.85.

The system of equations has exactly one solution.

Based on the information given, the equation is illustrated as:

2x - 3y = -4

-3x - 3y = 3

Add both equations

5x = -1

Divide

Since 2x - 3y = -4

2(-1/5) - 3y = 4

-2/5 - 3y = 4

3y = -2/5 - 4

Now, if the original coordinates of the figure are (x, y), as given in all the options, let us look at the effect of the transformation.

3 units right the x coordinate will increase by 3 units

thus x becomes (x + 3)

2 units down = the y coordinate will decrease by 2 units

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific values in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables. In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

The solution to the equation based on the description given is: n = -16.

First, we need to translate each given statement into algebraic expressions.

"11 less than 3 times n" can be translated as: 3 × n - 11 = 3n - 11

"75 less than the product of -1 and n" would be translated as: (-1)(n) - 75 = -n - 75.

It is stated that both statements or description are the same. This means, they are equal to each other. Therefore, the equation that would be formed is:

3n - 11 = -n - 75

Solve for n

3n - 11 + n = -n - 75 + n [addition property of equality]

4n - 11 = - 75

4n - 11 + 11 = - 75 + 11 [subtraction property of equality]

The measure of ∠A = ∠67°.

Complementary angle

The sum of two angles is equal to 90 degrees is called a complementary angle.

Here it is given that ∠A and ∠∠B is a complementary angle

So from this, we have

m ∠A + m ∠B = 90°

m ∠A = (7x + 18)°

m ∠B = ( 5x - 12)°

So we have,

(7x + 18)° + ( 5x - 12)° = 90°

(12x + 6 )° = 90°

12x = 84°

x = 7°

Now we will put the value of x in the mA equation,

mA = (7x + 18)°

     = (7× 7 + 18)°

     = (49 + 18)°
