The value of x is -1 4/5 i.e, Therefore, the correct option is A

Define Algebraic Expression

The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it. In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.).

Given expression,

-2/9 x=2/5

Isolate the variable, x

x = (2 * 9) / ( 5 * -2)

x = - (9/5) or -1 4/5

Hence, the value of x is -1 4/5 i.e, option(A)

What is a graph?

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Given, y = (x - 1).

What is the slope NEED HELP PLEASEEEEEEEE

Answers

The slope of the graph above is [tex]-\frac{4}{3}[/tex]

How to find the slope of a line?

The slope of a line is the change in the dependent variable with respect to the change in the independent variable. The slope of a line is rise over run.

Therefore,

slope = m = y₂ - y₁ / x₂ - x₁

Hence, using the coordinates on the graph let's find the slope of the graph.

(-2, 1)(1, -3)

Therefore,

x₁ = - 2

x₂ = 1

y₁ = 1

y₂ = - 3

Hence,

[tex]slope = \frac{-3-1}{1-(-2)}[/tex]

[tex]slope = \frac{-4}{1+2}[/tex]

big ben, the nickname for the clock in elizabeth tower (named after the queen in 2012) in london, has an hour hand 2.70 m long with a mass of 60.0 kg and a minute hand 4.50 m long with a mass of 100 kg (figure). calculate the total rotational kinetic energy of the two hands about the axis of rotation. (you may model the hands as long, thin rods rotated about one end. assume the hour and minute hands are rotating at a constant rate of one revolution per 12 hours and 60 minutes, respectively.)

Answers

The hour hand is 2.70 m long and minute hand is 4.50m long with mass of 60 kg and 100 kg. Therefore. Total angular momentum is 1.2 kgm²/s.

Mass of Hour hand = 60 kg

length of hour hand = 2.70 m

Now,

Moment of inertia of the hour hand is given by:

                         I = mL²/ 3

                         I = 60(2.70)²/3

                         I = 145.8 kgm²

Now,

The angular speed of hour hand is:

                           ω = 2π/ T

                          ⇒ ω = 2π / 12×3600

                          ⇒ ω = 1.45 × 10⁻¹ rad/s

Now,

Angular momentum is given as:

L₁ = Iω = 145.8 × 1.45× 10⁻¹

           = 0.021 kgm²/s

Mass of minute hand = 100 kg

length of minute hand = 4.50 m

Now,

Moment of inertia of the minute hand is given by:

I = mL²/ 3

I = 100(4.50)² /3

I = 675 kgm²

Now,

The angular speed of minute hand is

ω = 2π/ T

ω = 2π / 60× 60

ω = 1.74 × 10⁻³ rad/s

Now,

Angular momentum is given as:

L₂ = Iω = 675 × 1.74 ×10⁻³

           = 1.178 kgm²/s

Total angular momentum is given as

L = L₁ + L₂

  = 0.021 + 1.178

  = 1.2 kgm²/s

What is the equation of the line that passes through the point (-4,5) and has a slope of 3/4

Answers

Answer:

y = 3/4 x + 8

Step-by-step explanation:

y-5 = 3/4 (x-(-4)

y - 5 = 3/4 (x+4)

y - 5 = 3/4 x + 3

Y = 3/4 x + 3 + 5

y = 3/4 x + 8

Answer:

(-4,5) x = -4 and y = 5

use y = mx + c formula

so 5 = 3/4 (-4) +c

5 = -3 + c

5 + 3 = c

so c = 8

y = 3/4x + 8

Answers

According to the circle, if 8 points in a plane are chosen to lie on or inside a circle of diameter 2cm then show that the distance between some two points will be less than 1cm.

Circle:

Circle refers the round shape that has no corners or line segments. And it is a closed curve shape in geometry.

Given,

Eight points are in/on the circle of radius 1cm.

Here we need to show that distance between some two points is less than 1cm.

Let us consider the points be p1,p2,…,p8

Noe, we have to place the point p8 at the center of the circle and placing other seven points on the periphery of the circle, at equal distances

Here we have to remember that we are required to prove that there are at least a pair of points whose distance from each-other is less than 1cm.

So, now we have one point at the center and seven at the periphery of the circle.

Based on this the heptagon which will be formed by joining the seven points on the circle will have all its side equal in length.

Then the length of the side of the heptagon is less than 2π/7 cm which is less than 1cm.

Therefore, if we replace the position of any point then too we get a pair of points whose distance from each-other is less than 1cm.

The expectation of should reach 50% on average as N increases.

To properly test an App Inventor PRNG, you must test both the Random Integer and Random Fraction blocks along with the Random Fraction and Random set speed to blocks. Create dice simulations to get better than 50/50 predictions and reuse dice simulators for all combinations of different App Inventor random blocks.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

A package of Brand Y costs $7 and contains 10 oz of phosphates and 5 oz of nitrates.

The lawn requires at least 60 oz of phosphates and 40 oz of nitrates.

Let the number of Brand X packages be, x

the number of Brand Y packages be, y

According to the question,

12x + 10y ≥ 60 = 6x + 5y ≥ 30

10x + 5y ≥ 40 = 2x + y ≥ 8

x ≥ 0

y ≥ 0

Z = 16x + 7y

On solving the equations, we get

6x + 5y = 30

6x + 3y = 24

On subtracting, we get

2y = 6

y = 3

and x = 2.5

So, minimum cost will be at (2.5 , 3) and the minimum cost be

Z = 16(2.5) + 7(3)

Z = 4 + 21

The values of x, y and z in the given Rhombus are

x = -98, y = 36 and z = -97/4.

Given, the figure shown is a rhombus

as, the opposite angles of the rhombus are equal

So, 3y - 1 = 107

3y = 107 + 1

3y = 108

y = 36

and (-x - 8) = (-4z - 7)

x + 8 = 4z + 7

x - 4z = -1

also, the sum of the opposite angles of the rhombus is 180°.

So, (-x - 8) + (-4z - 7) = 180

-x - 4z = 180 + 15

x + 4z = -195

On adding the equations, we get

Given a precondition or premise, a conclusion or logical consequence and a rule or material conditional that implies the conclusion given the precondition, one can explain the following.

Since the number of members of the band is <200. the members are arranged in rows and 3 will be left out

therefore assume the members on row are 200- 3= 197, but 197 is a prime number ,therefore we choose the closet number to 197 which is 196.

9,603.75 cm² is the area of the given triangle.

What are triangles?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. △ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane. Equilateral, isosceles, scalene and right-angled triangles are the four different forms of triangles.

So, the perimeter of the triangle is 392 cm.

The unequal side is 195.

Then, let the rest 2 sides be x, where x = x.

x + x + 195 = 3922x + 195 = 3922x = 392 - 1952x = 197x = 197/2x = 98.5

Now, we know that the rest 2 equal sides are of length 98.5 cm.

Area of triangle: 1/2 × base × height

Now, calculate the area as follows:

1/2 × base × height1/2 × 98.5 × 1951/2 × 19,207.59,603.75
