Answer:

  (x, y) = (3, 5)

Step-by-step explanation:

Equate the two expressions for y and solve for x.

  x +2 = 2x -1

  3 = x . . . . . . . . add 1-x

  y = 3 +2 = 5 . . . . using the first equation

The solution is (x, y) = (3, 5).

Step-by-step explanation:

The argument of the complex number z=√2/2 - √2/2i is π/4. The correct option is A.

A complex number is a number system element in mathematics that extends the real numbers with a specific element denoted known as the imaginary unit and satisfies the equation.

The argument of a complex number z, in mathematics, is the angle formed by the positive real axis and the line connecting the origin and z, represented as a point in the complex plane.

Given that the complex number is z=√2/2 - √2/2i. The argument of the complex number is calculated as,

θ = tan⁻¹ ( b / a)

θ = tan⁻¹ ( √2/2 / √2/2)

θ = tan⁻¹ (1)

θ = 45°

θ = π / 4

With maintaining the given proportion the number of people who will contract the viral disease among 30,000 people will be 450.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

Three out of every 200 people contract the viral disease.

Ratio = 3/200

With the same ratio,

x/30000 = 3/200

x = (3/200)30,000

x = (3/2)300

x = 900/2 = 450

Hence "With maintaining the given proportion the number of people who will contract the viral disease among 30,000 people will be 450".

The cost of each entity: each pen is $[tex]1.75[/tex], each folder is $[tex]2.50[/tex], and each notebook is $[tex]1.75[/tex].

Let's assign variables to the costs of each supply:

Let the cost of each pen be P dollars.

Let the cost of each folder be F dollars.

Let the cost of each notebook be N dollars.

According to the given information, we can form the following equations:

For Shane:

[tex]4P + 3F + 2N = 12.25 (Equation \ 1)[/tex]

For Cheryl:

[tex]4F + 6N = 22 (Equation \ 2)[/tex]

For Isaiah:

[tex]2P + F + 3N = 10.25 (Equation \ 3)[/tex]

To solve this system of equations, we can use substitution or elimination method.

Using the elimination method, let's multiply Equation 2 by 2 and Equation 3 by 4 to eliminate F:

[tex]8F + 12N = 44 (Equation \ 4)\\8P + 2F + 12N = 41 (Equation \ 5)[/tex]

Now, subtract Equation 4 from Equation 5 to eliminate F:

[tex]8P + 2F + 12N - (8F + 12N) = 41 - 44\\8P - 6F = -3[/tex]

Simplifying further, we have:

[tex]8P - 6F = -3 (Equation \ 6)[/tex]

Now, let's multiply Equation 1 by 4 and Equation 3 by 3 to eliminate N:

[tex]16P + 12F + 8N = 49 (Equation \ 7)\\6P + 3F + 9N = 30 (Equation \ 8)[/tex]

Now, subtract Equation 8 from Equation 7 to eliminate N:

[tex]16P + 12F + 8N - (6P + 3F + 9N) = 49 - 30\\10P + 9F - N = 19[/tex]

Simplifying further, we have:

[tex]10P + 9F - N = 19 (Equation \ 9)[/tex]

Now we have a system of equations consisting of Equation 6, Equation 9, and Equation 2:

[tex]8P - 6F = -3 (Equation \ 6)\\10P + 9F - N = 19 (Equation \ 9)\\4F + 6N = 22 (Equation \ 2)[/tex]

To find the values of P, F, and N, we can solve this system of equations using any suitable method, such as substitution or elimination.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

A toy robot moves 10 feet in 12 seconds at a constant speed.

Now,

At a constant speed,

In 12 second = 10 feet

So, In 1 second = 10 / 12 feet

                        = 0.83 feet

Thus, The robot move 0.83 feet in one second.

Use Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + ([tex]\sqrt{5}[/tex] )² = 7²

x² + 5 = 49 ( subtract 5 from both sides )

x² = 44 ( take the square root of both sides )
