What is the solution of the equation 2x y 5 and 3x 2y 4?.

Using factoring, we do the following actions to make rational expressions simpler:

As much as you can, factor the numerator and denominator. Any factors that appear in both the numerator and the denominator should be eliminated. Your expression gets simplified as a result. How is an expression factorized:

Step 1 is to identify the expression's prime factors.

Step 2: Find the GCF by enclosing the common factors.

Write each term in the expression as a combination of the GCF and the final factor in step 3.

Step 4: Simplify the equation by applying the distributive property.

Answer: Positive

Hope this helps :)

Step-by-step explanation:

When multiplying or dividing with two negative numbers, the product/quotient will always be positive.

-8/-4 = 2

Answer: Positive

Step-by-step explanation:

Example for multiplication:

Imagine 4 friends that owe you $8 each.

Each friend that pays you back represents their payback as -$8.

-$8 * 4 friends = -$32 that they owe you.

The moment they give it back, you now have +$32. The Debt was taken away.

Example for Division:

Imagine splitting 8 dollars in debt with 4 friends, each friend then has $2 in debt. Each payback means you have +$2.

Another visual way to think of this is with Number Lines.

On a number line, when you multiply by a larger absolute value the numbers get bigger and go farther away from 0. So, taking a negative and multiplying it by a positive makes it MORE negative, as opposed to multiplying it by negative and then it reflects the number line,

The given equation y = -3x + 5 has infinitely many solutions.

We have linear equation y = -3x + 5

We need to encounter how many solutions can satisfy the given equation. 

We know that,

y = -3x + 5 is a linear equation in two variables in the form ax + by + c = 0

For x = 0, y = 0 + 5 = 5. Therefore, (0, 5) is one solution.

For x = 1, y = -3 × 1 + 5 = 2. Therefore, (1, 2) is another solution.

For y = 0, -3x + 5 = 0, x = 5/3. Therefore, (5/3, 0) is another solution.

Clearly, for different values of x, we get different values for y. Thus, any value substituted in the place of x in the given equation will form another solution for the given equation. So, there is no limitation to the number of different solutions obtained by substituting real values for x in the given linear equation. Thus, a linear equation in two variables can have infinitely many solutions.

Thus, y = -3x + 5 has infinitely many solutions.

So, in 4 years, there will be 1176 people attending.

To find out how many people will be attending in 4 years, you need to determine the total decrease in attendance over that time period. The attendance is decreasing at a rate of 0.5% per year, so over 4 years, the decrease in attendance will be 4 years x 0.5% = 2%

To find out how many people will be attending in 4 years, you can then subtract the 2% decrease from the current attendance of 1200 people:

1200 x (1 - 0.02) = 1176 people

So, in 4 years, there will be 1176 people attending.

You must ascertain the overall drop in attendance over that time span in order to calculate the number of attendees in 4 years. If enrollment drops by 0.5% annually, it will drop by 2% over the course of four years (4 years x 0.5%).

Then, from the present attendance of 1200 people, subtract the 2% decline to determine how many attendees there will be in 4 years:

1200 times (1-0.02) ≈ 1176 individuals

Therefore, there will be 1176 attendees in 4 years.

The correct expression to solve te sum of polynomials is [(-3x)+(-8x)]+4x+[9+5] (D).

To solve any polynomials problems, it is important for us to take a close look on the orders of each number. For the sum and substraction operation, we need to categorize each number based on its orders.

From the case, we have a problem as:

(9 - 3x²) + (-8x² + 4x  + 5)

We can categorize each order:

Order 2 = (-3x²) and (-8x²)

Order 1 = 4x

Order 0 = 9 and 5

Hence, we can solve the problem as:

(9 - 3x²) + (-8x² + 4x + 5)

= [(-3x²) + (-8x²)] + 4x + (9 + 5)

= -11x² + 4x + 14

By visually counting the number of times the curve crosses vertical lines, the vertical line test is a graphical approach for verifying whether a curve in the plane accurately depicts the graph of a function. the graph of a function can only be intersected by any vertical line in the plane once as a result.

A graph must satisfy the vertical line test in order to be considered a function representation. The vertical line test requires that the line from the x-axis only once crosses an associated y-value.

Graphs (a), (c), and (e) fail the vertical line test, indicating that they do not reflect a function.

What is commutative property in math?

This law simply states that with addition and multiplication of numbers, you can change the order of the numbers in the problem and it will not affect the answer. Subtraction and division are NOT commutative.

The commutative property of real numbers states that for any real numbers a and b, a + b = b + a and a * b = b * a. In other words, the order in which two real numbers are added or multiplied does not change the result. This property applies to both addition and multiplication of real numbers.

Complex fractions are called complex because they contain one or more fractions within the numerator and/or denominator of the fraction. These fractions within the fraction make the fraction more complex or difficult to simplify than a regular fraction, which only has a single numerator and denominator.

The term "complex" in mathematics often refers to something that is composed of multiple parts or layers, and that requires more steps or understanding to work with or solve.

In this case, the presence of one or more fractions within the fraction makes it more complex than a regular fraction, hence the name "complex fraction."

Another reason for the term complex is that the fractions in the numerator and denominator may have different or even the same variables, making it difficult to cancel them or simplify the expression.

In the word problem the number of the adult ticket is 225.

What is word problem?

Word problems are often described verbally as instances where a problem exists and one or more questions are posed, the solutions to which can be found by applying mathematical operations to the numerical information provided in the problem statement. Determining whether two provided statements are equal with respect to a collection of rewritings is known as a word problem in computational mathematics.

Here total number of tickets = 516.

Which is contains adult and students tickets. Then let us take x is number of adult ticket and y is number of student tickets then,

=> x + y = 516 ------> 1

Now  there were 66 more student tickets sold than adult tickets then

=> y = x+66 -----> 2

Now put 2 into 1 then

=> x+66+x = 516

=> 2x = 516-66 = 450

=> x = 225.

Now put x = 225 into then

=> y = 225+66 = 291.

Possible way in which two consecutive odd numbers are added to sum of 2023 is by evaluation using the formula (2n - 1) + (2n + 1) = 2023, so that we have 1010.5 + 1012.5 = 2023

Consecutive odd numbers are a sequence of numbers that are separated by a difference of 2 and are all odd numbers. For example the first four odd numbers are: 1, 3, 5, and 7. Odd numbers can be generated using the formula 2n -1.

We shall represent the first odd number with (2n - 1) so that the two consecutive odd numbers will be expressed as:

(2n - 1) + (2n + 1) = 2023

2n + 2n = 2023

4n = 2023

n = 2023/4 {divide through by 4}

n = 505.75

Therefore the two consecutive odd numbers added to sum of 2023 are derived as:
