Step-by-step explanation:

The linear function in the option is − x / 3 + y / 7 = 11.

A linear function is a function that represents a straight line on the coordinate plane.

Linear function can be represented in slope intercept form as follows:

y = mx + b

where

Therefore, let's select the linear function from the options:

− 3 / x + y / 7 = 11

-3x⁻¹ + 1 / 7 y = 11 (Not a linear function)

− x / 3 + 7 / y = 11

- 1 / 3 x + 7y⁻¹ = 11 (Not a linear function)

− x / 3 + y / 7 = xy (Not a linear function)

− x / 3 + y / 7 = 11

- 1 / 3 x + 1 / 7 y = 11 (This is the linear function)

Answer:

The area of a triangle can be calculated using the formula A = 1/2 * b * h, where b is the base and h is the height of the triangle. In this case, if the base of the triangle is H units and the height is 7 units, the area of the triangle would be A = 1/2 * H * 7 = 3.5 * H.

When we subtract 3xy from 5 we will get 3xy - 5.Both are different 3xy is a polynomial in xy and 5 is a constant we can not simplify further.

First, let's try to learn subtraction in the case of polynomials.

3xy is a polynomial.

5 is a constant.

Polynomials can be subtracted using a method that involves changing the signs to the opposite sign. The process resembles adding polynomials. Depending on the specific equation, we transform the sign while subtracting polynomials to either positive or negative. Learn more about subtracting polynomials, their techniques, procedures, and examples by reading on.

For instance, subtract 5x + 8y - 20z from 4x - 10y + 15z.

The polynomials should first be arranged in standard form. In this illustration, it has already been set up.

Place them horizontally in step two.

(4x - 10y + 15z) - (5x + 8y - 20z)

Step 3: By using parenthesis, modify the second polynomial's sign.

4x-10y-15z, and 5x+8y 20z

Step 4: Group terms that are similar together.

4x - 5x - 10y - 8y + 15z + 20z

Step 5: Resolve the problem

-x - 18y + 35z

As a result, we get -x - 18y + 35z when we subtract 4x - 10y + 15z from 5x + 8y - 20z.

In the same way, if we subtract 3xy from 5 we will get 3xy - 5.

In order for an expression, such as x² + 4x + , to become a perfect square trinomial, it must be in the form of a² + 2ab + b².

Perfect squares are whole numbers that are the result of multiplying a given number by itself. For example, 4 is a perfect square because it is the result of multiplying 2 by itself. Similarly, 9 is a perfect square because it is the result of multiplying 3 by itself. Other examples of perfect squares include 16 (4x4), 25 (5x5), 36 (6x6), and so on.

To do this, you must factor the expression. In this case, the expression can be factored into (x + 2)².

Once the expression has been factored into a perfect square trinomial, it can be written as (x + 2)².

This is a perfect square trinomial because it represents the area of a square, as the length of each side is equal to (x + 2).

So the number of parcels that Helen delivered on Monday ​is 120 parcels.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

An equality of two ratios is a percentage. We use proportions to construct comparable ratios and find solutions to problems involving unknown numbers.

If on Wednesday Helen delivered 50% fewer parcels than on Tuesday, then on Tuesday Helen delivered 72 / (1 - 0.5) = 72 * 2 = 144 parcels.

On Tuesday Helen delivered 20% more parcels than on Monday, so the number of parcels Helen delivered on Monday is (144 / 1.2) = 120

So Helen delivered 120 parcels on Monday.

Step-by-step explanation:

y=16, r=-21/2

This system of equations have no solution, the correct option is A.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree. A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.

We are given that;

y = 12 + 1 + 3

y = -2r – 5

Now,

We can simplify the first equation by adding 12 + 1 + 3 to get y = 16. Then we can compare the coefficients of r and y in both equations.

We can see that the coefficients of r are different (-2 and 0), but the coefficients of y are the same (1 and 1).

This means that the graphs of the equations are parallel lines with different y-intercepts (16 and -5).

Therefore, the answer will be the system of equations has no solution.

The equation a²-4=0, which corresponds to the factorization of a²-4= (a+ 2)(a-2)

Factorization refers to the process of breaking down a mathematical expression into simpler parts that can be multiplied together to give the original expression. For example, factorizing the expression x² + 4x - 12 would give (x - 3)(x + 4) as the factors.

In algebra, factorization is used to simplify expressions and to find the solutions of equations. For example, in the quadratic equation ax² + bx + c = 0, the first step in solving the equation is to factorize the quadratic expression ax² + bx + c. Once this is done, it becomes easier to find the solutions of the equation by setting each factor equal to zero and solving for x.

Factorization can also be used to simplify expressions in other branches of mathematics, such as number theory. For example, the prime factorization of a composite number is the representation of that number as a product of prime numbers.

Given:

The equation a²-4= (a+ 2)(a-2) is a factorization of a quadratic expression. It states that the expression a²-4 can be represented as the product of two binomials, (a+ 2) and (a-2).

This can be visualized as the graph of a parabola, where the x-intercepts of the parabola are -2 and 2. These are the solutions of the equation a²-4=0, which corresponds to the factorization of a²-4= (a+ 2)(a-2)
