OYes, k= 9/4
O Yes, k = 4/9
O Yes, k = 9
O Not direct variation

Answers

Yes the the equation is following direct variation. Correct option is A, Yes, k = 4/9

What is Direct Variation?

The change in one quantity as a result of the change in another is known as direct variation. This implies that if one quantity increases or decreases, the other must do the same.

Direct variation describes how one quantity directly affects the other when it varies. The precise reverse of this is called inverse variation. You will discover what direct and inverse variants are in this article, along with various cases that have been solved.

4y = 9x

standard equation for direct variation is y = kx

y = 9/4 x

On comparing the equation with standard equation,

k = 9/4

Hence, the equation is following direct variation

Any equation in algebra that can be written in standard form as where x is an unknown and a, b, and c denote known numbers, where a 0 is a quadratic equation.

x ax2 + bx + c = 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. a 0. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem.

When a problem is factorable, factoring is often the quickest and simplest solution. Factoring won't help us because many times the quadratic we're working with can't be factored. Therefore, it is quick and simple when it is useable but not always factorable.

In proportion , [tex]1\frac{3}{4}[/tex] pound of ground beef requires [tex]1\frac{1}{20}[/tex] cup of breadcrumbs.

What in mathematics is a proportion?

A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4)

It is given that Dominic uses 3/4 cups of breadcrumbs for every [tex]1\frac{1}{4}[/tex] pounds of ground beef. Therefore for 1 pound of ground beef he will required .

[tex]1\frac{1}{4}[/tex] → 3/4

5/4 → 3/4

For the function g(x) = x6, if the domain of x is R, what is the range of g (x)?

Answers

the range of the function g(x) = x^6 is: R: [0, ∞)

What is the range of the function?

Here we have the function:

g(x) = x^6

First, notice that we have an even exponent. This means that the outcome of the function will always be a positive number, then the minimum of the range is:

g(0) = 0^6 = 6

And we don't have a maximum, the function tends to positive infinity in both ends (as x → -∞ and as x → ∞).

The third quartile of the date is Q₃=75

What is Quartile in Maths.?

The numbers known as quartiles are used to divide the provided data set into four equal portions, or three points. Thus, the values that split the provided data into three quarters are known as quartiles. The center point of distribution is shown by the middle portion of the quartiles. The interquartile range is determined by the difference between the higher and lower quartiles so established.

Data 26, 34, 38, 49, 65, 75, 81

First arrange the data from smallest to greatest

26, 34, 38, 49, 65, 75, 81

Then find the median of the data,

Since, the data is in odd numbers median is mid term i.e. 49.

To find the third quartile we take the upper half of data

Upper half of data set, 65, 75, 81

Third quartile is the median of the upper half of the data.

Median of upper half is

Q3 =(3+1)th

Q3 = 2th term

Q3 = 75term

The greatest possible sum for the two integers ( c and d) is 1.

Number Classification

Whole Numbers - They are the numbers represented by positive real numbers where the fractions and decimal numbers are not included.

Integer Numbers - They are the whole numbers. They are represented by zero, positive and negative numbers.

Opposite numbers - They are numbers that the distance to 0 is equal. The numbers are classified as the opposite when the sum between them is equal to zero (0).

The question gives:

c and d ar integers;c*d = -6

The possible values for c and d for a product equals -6 are:

option 1 c= -2 and d= 3option 2 c= -3 and d= 2option 3 c= 2 and d= -3option 4 c= 3 and d= -2

Now you should sum the possible values of c and d for each option.

After a 60% reduction, you purchase a new sofa on sale for $280. What was the original price of the sofa?

Answers

The original price of the Sofa is $620

How to calculate the original price ?

The original price is reduced by 60%

After this reduction the price reduced to $280

Therefore the original price can be calculated as follows

The first step is to subtract 60% from 100%

= 100-60

= 40%

The original price can be calculated as follows

280 × 100/40

= 28,000/40

= 700

Hence the original price of the sofa is $700

By factor decomposition, area of a square and power and root properties, the length of the side is between 72 yards and 76 yards. (Correct choice: B)

What integers are the limits between the length of an equivalent square side of a given area?

The area of a triangle is equal to the square of its side length and the area of land is a composite number, that is, a product of prime numbers. By factor decomposition, the equivalent form of 5,280 square yards is:

5,280 = 2⁵ × 3 × 5 × 11

Then, the equivalent side is equal to the square product of the product:

x = √(2⁵ × 3 × 5 × 11)

x = √(2⁴) × √(2 × 3 × 5 × 11)

x = 2² × √(2 × 3 × 5 × 11)

x = 4√330

As for √330 is between √324 = 18 and √361 = 19, then the length of the side is between 72 yards and 76 yards.

Two pages that face each other in a book have 349 as the sum of their page numbers. What is the number of the page that comes first?

Answers

Answer: 174

Step-by-step explanation:

For this problem, let's divide the number by two since we know it's a combination of two numbers in a series as they are two consecutive book pages.

349 / 2 = 174.5

Note, that the number we have is a decimal, and page numbers cannot be partial numbers, they must be integers. With this, we can take the lower and the upper of our decimal numbers to retrieve the two-page numbers.

174.5 (Upper) ==> 175

174.5 (Lower) ==> 174

With this, we can verify these numbers have a sum of 349.

175 + 174 =? 349

349 == 349

So indeed, these numbers are a sum of 349. Now that we know these are our page numbers, we know 174 will come before 175 since page numbers are sequential.

Given that

The co-ordinates of line is (0,0) and (2,1).

To find

The points that lie on the line, and The relationship between the coordinates x and y.

So, according to the question

We have,

The X and Y co-ordinates of line (0,0) and (2,1).

For finding any point that lie on line, first we have to find the slope of given line,

So, we know that

slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Where,

x₁ = 0 and x₂ = 2

y₁ = 0 and y₂ = 1

Now, putting the values, we will get

(m) = [tex]\frac{1-0}{2-0}[/tex] = [tex]\frac{1}{2}[/tex]

m = [tex]\frac{1}{2}[/tex]

We know that, the equation of line
