Answer:

(2,-5)

Step-by-step explanation:

find the coordinates which forms rectangle with othe given points

The coordinates of the fourth vertex of the rectangle are (2, -5).

A rectangle is defined as a four-sided shape with opposite sides that are equal in length and parallel to each other.

We have to determine the fourth vertex of the rectangle.

As we know that the opposite sides of a rectangle are equal.

The x-coordinate of the second vertex (2,4) is equal to the x-coordinate of the fourth vertex.

So, the x-coordinate of the fourth vertex = 2

The y-coordinate of the third vertex (-2,-5) is equal to the y-coordinate of the fourth vertex.

So, the y-coordinate of the fourth vertex = -5

Therefore, the coordinates of the fourth vertex of the rectangle are (2, -5).

The cosine of a right-angled triangle is defined by the trigonometric word “cos” meaning.The neighboring base-to-hypotenuse ratio is known as the cos function in a right-angled triangle.

It aids in determining the triangle's side lengths regardless of the provided angle. If the angle between the neighboring side and the hypotenuse of a right triangle is, we can write this using the cos function.

In a right triangle, the ratio between an angle's adjacent side and the hypotenuse is known as the cosine of the angle. It is written as:

Cos = Base of the right-angled triangle/ Hypotenuse of the right-angled triangle.

The slope of y=-10x is -10.

The slope of a linear equation in the form of y = mx + b is represented by the coefficient of x, which is also known as the "slope" or "rate of change." In this case, the coefficient of x is -10.

This means that for every unit increase in x, there is a corresponding decrease of 10 units in y. In other words, the line represented by this equation has a negative slope, meaning it slopes downwards as it goes from left to right.

A linear equation is an equation that can be written in the form of y = mx + b, where m is the slope (or rate of change) and b is the y-intercept (the point where the line crosses the y-axis). Linear equations represent straight lines on a graph, and their slope and y-intercept can be used to determine the characteristics of the line, such as its direction and position.

The solutions to the nonlinear system of equations are (x₁, y₁) = (1 + √14 / 7, - 1 + 3√14 / 7) and (x₂, y₂) = (1 - √14 / 7, - 1 - 3√14 / 7).

In this problem we find the case of a system of two equations formed by a linear equation and a quadratic equation that can be solved by means of algebra properties. First, write the entire system of equations:

3 · x - y = 4

2 · x² + y² + x · y = 6

Second, clear y in the first equation:

y = 3 · x - 4

Third, substitute in the second equation:

2 · x² + (3 · x - 4)²  + x · (3 · x - 4) = 6

2 · x² + 9 · x² - 24 · x + 16 + 3 · x² - 4 · x = 6

14 · x² - 28 · x + 10 = 0

By quadratic formula:

x₁ = 1 + √14 / 7 or x₂ = 1 - √14 / 7

Fourth, find the possible values for y:

y₁ = 3 · x₁ - 4

y₁ = 3 · (1 + √14 / 7) - 4

y₁ = - 1 + 3√14 / 7

y₂ = 3 · x₂ - 4

y₂ = 3 · (1 - √14 / 7) - 4

y₂ = - 1 - 3√14 / 7

Fifth, write the solutions:

(x₁, y₁) = (1 + √14 / 7, - 1 + 3√14 / 7), (x₂, y₂) = (1 - √14 / 7, - 1 - 3√14 / 7)

By evaluating the system of inequalities we will see that the point (0, 1) is not a solution.

A point (x, y) is a solution of the system of eqations if, when we replace both values, both inequalties are true.

Replacing the values of the point (0, 1) we will get:

Answer: 6

Step-by-step explanation:

When solving this problem, it is important to remember the rules for when we add a negative and subtract a negative. When we add a negative (+ -), we are essentially going to keep the sign attached to the number. In this case, we would still subtract. When subtracting a negative (- -), the signs cancel out, so will add the number instead. With that in mind, we can rewrite the equation and solve it as follows:

O₂ is two moles.

The molecular mass of an element is described as the sum of the masses of all the atoms present in the molecule.

Molecular mass is acquired by adding the atomic masses of all atoms with the number of atoms in the molecule.

O₂ has two atoms, so a mole of O₂ would have 1 mole of O₂ molecules, and when broken down into atoms, 2 moles of atoms.

Think about it like pairs of shoes. If you have 6 pairs of shoes, you have 12 pairs of shoes.

CO₂ has 3 atoms, 2N₂0 has 3 atoms, and there are already 2 moles, so that would be 6 moles of atoms; 2NaCl has 2 atoms but again, that 2 indicates that you'd have 4 moles of atoms, and H₂SO₄ has 7 atoms.

The percentage of Venus's year to mercury's year is 39.1%

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction - three for the price of one! To change the percentage to a fraction, just put the percentage number in the numerator and 100 in the denominator.

Venus year is 88 earth days and mercury is 225 earth days.

To find the percentage of venus's year to mercury's we divide the Venus's year by mercury and multiply by 100

Then , 88/225 ×100 = 39.1 %

The graph of f(x) = 2x + 3 is a linear function and its y-intercept is y = 2x + 3.

Any function is referred to as linear if it represents a straight line on the coordinate plane. For instance, the linear function represented by the equation y = 3x – 2 looks like a straight line on a coordinate plane. Due to the fact that f(x) can substitute for y, this function can be written as f(x) = 3x - 2.

First find the slope of the line

y - y₁ = m(x - x₁)

0 - 3 = m(-1.5 - 0)

m = 2

From the graph, we can take any of the two points i.e.(0, 3) and put it in slope formula

y - y₁ = m(x - x₁)

So,

y - 3 = 2(x - 0)

Product rule example is f(x) = (3x - 2x2)(5 + 4x).

Following the Product rule we have

f ' (x) = (3x - 2x2)(0 + 4) + (5 + 4x) (3 - 4x)

Simply put, a product is the outcome of multiplying two functions. This rule, which was developed by Gottfried Leibniz, enables us to compute derivatives that we don't want (or are unable to) multiply quickly.

When there is no solution to a system called an inconsistent system of equations.

A linear equation in two variables is in the form ax + by + c = 0 where a, b, c ∈ R, a, and b ≠ 0. An inconsistent pair of linear equations is named a linear equation system with no solution. When we think of a system of linear equations, we are able to compare the coefficients of the equations and find whether it is a system of equations with no solution.

Assume the pair of linear equations in two variables, x and y.

a₁x + b₁y + c₁ = 0

a₂x + b₂y + c₂ = 0

Where a₁, b₁, c₁, a₂, b₂, c₂ stand real numbers.

Note that, a₁² + b₁² ≠ 0, a₂² + b₂² ≠ 0
