The pairs which cannot be written or expressed in the notation of (a,b) and do not follow a specific order are not ordered pairs .

What are Ordered Pairs ?

The Ordered Pair is defined as a pair of elements that have specific importance for order of their placements. Ordered pairs are used in coordinate geometry to represent a point on a coordinate plane.

So , the numbers that do not follow the specific order of placements cannot be called as Ordered Pairs .

Two Ordered Pairs [tex](a_{1} ,b_{1} )[/tex] and [tex](a_{2} ,b_{2} )[/tex] can be considered as equal if and only if [tex]a_{1} =a_{2}[/tex] and [tex]b_{1} =b_{2}[/tex] .

Every point on Coordinate Plane is represented by ordered pair (x, y) where "first element x" is called x coordinate and "second element y" is called y-coordinate.

The requried equation used to find the total cost of care of dogs is given as, 1. y = 35x  for 0 ≤ x ≤3 2. y = 35 + 25x for 3 < x. None of the op[tions are correct.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Emma takes care of dogs while their owners are on vacation. She charges $35 for each of the first 3 days she takes care of a dog and $25 for each day thereafter.

Two equations will be formed,
1. y = 35x  for 0 ≤ x ≤3
2. y = 35 + 25x for 3 < x

Thus, the requried equation used to find the total cost of care of dogs is given as, 1. y = 35x  for 0 ≤ x ≤3 2. y = 35 + 25x for 3 < x. None of the op[tions are correct.

The range of y = log subscript 8 baseline x is all real numbers.

The range is a set of all the defined values of y-correspond to the domain. In this case, to find the range of the function y = log subscript 8 baseline x, we need to draw the graph of the function.

The graph is attached.

Now, because of the base of the logarithm is 8 > 1; so, the graph is raising and passes through the point (1,0).

So, the domain of this function is:

x > 0

And, the range of this function is:

y ∈ (–∞,∞)

Prime multiples of number 3 is number 3 itself as other multiples of three are representing composite numbers.

As given in the question,

Given number is equal to :

3

Multiples are those numbers which we get when we multiply the given number by any other integer.

Multiples of three are equal to :

3 × 1 = 3

3 × 2 = 6

3 × 3 = 9

3 × 4 = 12

3 × 5 = 15

............... so on.

When we multiple 'n' by three we get 3n.

All other multiples have more than two factors that is one , three , and at least number itself.

So other multiples of three are composite numbers.

Prime multiples has only two factors one and number itself.

So, we have:

Height of 6 and bas of 9 units of the right triangle.

Pythagorean formula:

c=√a²+b²

Now, insert values and calculate as follows:

c = √a²+b²

c = √9²+16²

c = 18.35 units

The amount of money you must pay at the gas station could be represented using the variables y = price in dollars, x = gas in gallons, and a proportionality constant, k: y = kx.

Mrs. Tenon has spent $5 on 25 party favours.

Equation form of proportional relationships is written as y=kx.

If you substitute $5 for y and $25 for x in the formula for the proportional relationship above, you can find the value of the proportionality constant, or k.

$5=k(25)\sk=$5/25\s=0.2

0.2 is the proportionality constant. Thus, each party favour costs $0.20.

Let's say there are r party favours and the cost is c. c=0.2r

In the equation above, 40 should be substituted for r to get the price of 40 party favours: c=0.2 (60) = 12.00.

As a result, the cost for 40 guests is $ 8.00, and the cost for 60 party favours is $ 12.00.

From the information, the total measure of the angles is (n−2)·180°, where n=8. The term regular means all interior angle measures are the same.

It should be noted that in Mathematics, the value of the sum of angles is Illustrated in this case. We can determine each angle measure from the total angle measure thus:

(n - 2) × 180

n = 8

It should be noted that n in this case simply means the number of sides

Since FE bisects <DFG, then the value of x and measure of <DFG are:

a. x = 24

b. m<DFG = 106^o

An angle bisector is a straight line constructed in such a way that it divides a given angle into two equal measures.

Thus given that FE bisects <DFG, this implies that;

i. m<DFE ≅ m<EFG

So that,

3x - 19 = 2x + 5

collect like terms to have;

3x - 2x = 19 + 5

x = 24

To solve for x, the value of x is 24^o.

ii. To determine the measure of DFG;

On solving the provided question, we can say that multiplication of polynomial  3(8 + ) is 24+3

A polynomial is an algebraic expression in mathematics that solely uses the operations of addition, subtraction, multiplication, and powers of positive-integer variables. It consists of variables and coefficients.

For example, in the expression , x is the variable and coefficients of  and  are 1 and 2 respectively.

When we are asked to do multiplication of polynomials, we multiply term by term in the brackets until every term is multiplies with another in different bracket.

Like in 3(8 + ), we first multiply 3 with the first term inside the bracket, which is 8 and then we multiply 3 with the second term, which is b and maintaining the plus sign as it is.
