The k is not constant, so the table data does not display a proportional relationship.

What is the proportional relationship?

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.

Here, we have

Given:

x    y

4    1

5    64.125

6    216

10   1,000

A proportional relationship defines that two or more quantities vary directly with one another.

y is proportional to x if  y=kx  for all values of y and x, and k is the constant of proportionality.

for the first value on the tale

k = 1/4  =0.25

for second value

k = 64.125/5 = 12.825

Hence, the k is not constant, so the table data does not display a proportional relationship.

Five examples of polynomial are 3x, 5x + y, 2, 7x² - 3, and 8x⁵ - 2x³ + 2.

A polynomial is a mathematical expression that involves a sum of powers in one or more variables. The general form of a polynomial in one variable x is a_nx^n + a_{n-1}x^{n-1} + ... + a_2x^2 + a_1x + a_0, where n is a non-negative integer and the coefficients a_0, a_1, ..., a_n are real or complex numbers.

The solution set of the inequality g < 5 is all the values of g that are less than 5.

What exactly is a math graph?

The term "graph" has at least two separate meanings in mathematics. The word "graph" in elementary mathematics refers to a plot or a function graph. In mathematical terms, a graph is a collection of points and the relationships between a subset of those points (which may be empty).

To graph this solution set, we use a number line, and place an open dot at 5 to indicate that 5 is not included in the solution set. Then, we shade the portion of the number line to the left of 5, which represents all the values of g that are less than 5. The graph of the solution set would look like this:

(shaded area represents all the values of g that satisfy the inequality)

Note: The value 5 is not included in the solution set as the inequality is strict inequality.

According to the unitary method, the store that has the best deal is Store 1 and it cost $202.18

The term unitary method is known as a process of finding the value of a single unit, and based on this value.

Here we have the original prices of the rugs are as follows:

Store #1: $289

Store #2: $265

Store #3: $310

And the discount on each store is written as,

Store #1: 20% (decrease)

Store #2: 12%(decrease)

Store #3: 30%(increase)

And the tax details are given as,

Store #1: 8%

Store #2: 8%

Store #3: no tax.

Then the shipping and the handling charges is $5.9

Then the price for each of the store is calculated as,

=> Store 1 = 289 - [(289 x 0.20) + (289 x 0.08) + 5.9] = 202.18

=> Store 2 = 265 - [(265 x 0.12) + (265 x 0.08) + 5.9] = 206.1

=> Store 3 = 310 + (310 x 0.30) - 5.9 = 397.1

1.The circumferences of the two circles are 220 feet and 126 feet, respectively. We may think of a circle's circumference as a form of "perimeter."

2. The following is the radius of the circle made by Ana's brother in the blue car:

We know that the following formula determines a circle's circumference:

[tex]C=2\Pi \ r[/tex]

Then, we must get r by solving this equation. We know that C is 220 feet and pi is 3.14. Next, we have

[tex]220=2 \cdot \pi \cdot r \\\Rightarrow r=\frac{220}{2 \pi} \\\Rightarrow r=\frac{220}{2 \cdot 3.14} \\\Rightarrow r=35.0318[/tex]

The radius, rounded to the closest tenth, is RB = 35.0 feet (or 35 feet).

3. Using the same method, we can determine the radius of the circle that Ana's sister drew in the green automobile (she travelled 126 feet).

The methods used in factoring are Greatest Common Factor (GCF), Grouping Method, Using Identities, Factor Theorem, and Polynomial with Four Terms.

Greatest Common Factor (GCF): To factorise, We have to find out the greatest common factor, of the given polynomial.

a(b + c) = ab + ac

But in the matter of factorisation, it is just an inverse process;

ab + ac = a(b + c)

where p is the greatest common factor.

Grouping Method: This method is also stated to be factoring by pairs. In this method, the given polynomial is distributed in pairs to find the zeros. 

Factoring Using Identities: The factorisation can be accomplished also by using algebraic identities. The most typical identities used in terms of the factorisation are:

(α + β)² = α² + 2αβ + β²

(α – β)² = α² – 2αβ + β²

α² – β² = (α + β)(α – β)

Factor Theorem: For a polynomial g(x) of a degree greater than or equal to 1,

x - b is a factor of g(x), if g(b) = 0

If g(b) = 0, then x - b is a factor of g(x)

Where ‘b’ is a real number.

Factoring Polynomial with Four Terms:

For example, x³ + x² – x – 1 is the polynomial. 

Split the given polynomial into two parts.

(x³ + x²) + ( –x – 1)

We can see, from the first part, x² is the greatest common factor and from the second part, we can take out the minus sign. Thus,

x²(x + 1) - 1(x + 1)

Again, regrouping the terms as the factors.

(x² - 1) (x + 1)Therefore, the factorisation of x³+ x² – x – 1 gives (x² -1) (x+1).

2. The y-intercept is; c = 250

3. The distance traveled at the y-intercept is 0

4. The y-intercept represents the initial fee for the taxi

The equation of a straight line graph in the slope-internet format is;  y = m·x + c.

The graph in the question obtained from the graph in a similar question posted online, is a straight line graph

The equation of the graph is therefore of the form; y = m·x + c

Where;

m = The slope of the graph

c = The y-intercept

The points on the possible graph of the question are;

(0, 250), (0.8, 400)

The y-intercept of the graph is therefore;

(0, 250), c = 250

The slope of the graph is therefore;

(400 - 250)/(0.8 - 0) = 187.5

The equation of the graph is therefore;

y = 187.5·x + 250

The multiplicative inverse of -11/7 is "A. -7/11".

Step-by-step explanation:

The multiplicative inverse of a fraction is found by flipping the numerator and denominator. So, if a fraction a/b has a multiplicative inverse, then it must be true that:

a/b * (b/a) = 1

In this case, we want to find the multiplicative inverse of -11/7:

-11/7 * x = 1

So, we flip the numerator and denominator of -11/7 to find x:

x = -7/11

Therefore, the multiplicative inverse of -11/7 is -7/11, which is option A.

The equation (x-6)²(x+2)² can be factored by using the difference of squares factorization. This factorization states that for any two binomials a-b and a+b, their product can be written as (a-b)(a+b)= a²-b². In this case, we have (x-6)² and (x+2)², which can be factored as (x-6)² = (x-6)(x-6) = (x-6)², and (x+2)² = (x+2)(x+2) = (x+2)².

So, the equation (x-6)²(x+2)² can be factorized as (x-6)²(x+2)² = (x-6)² * (x+2).

The roots of the equation are the values of x that make the equation equal to zero. To find the roots of the equation, we set each of the factors to zero and solve for x.

Step-by-step explanation:

x = 4y - 3

2x +3y = 16

First, plug the equation x = 4y - 3 into the second equation so it looks like this:

2 (4y - 3) + 3y = 16    Now we only have one variable to solve for.

8y - 6 + 3y = 16    Simplify like variables

11y - 6 = 16     try to get y by itself

11y = 16 + 6

11y = 22     divide both sides by 11

y = 2

Now you can put Y back into the first equation

x = 4y - 3

x = 4(2) - 3

x = 8 - 3

x = 5

so the answer is x = 5 and y = 2

In essence, it is equivalent to 1/2 of base times height, or A = 1/2 b times h. A triangular polygon's base (b) and height (h) must be known in order to calculate its area.

Whether a triangle is scalene, isosceles, or equilateral, it can be used to solve any kind of triangle.

Be aware that the triangle's base and height are at right angles to one another. In square units, the area unit is measured (m2, cm2).

Example :

Consider this triangle with a base of 3 cm and a height of 4 cm. What is its area?

Employing the formula,

Triangle's area is equal to half of b times h.

= 6 cm2.

In addition to the method mentioned above, Heron's formula can be used to determine a triangle's area when we know the lengths of its three sides.
