The graph's representation of the inequality system is

y≤3x-2 and y≥-4x+2. So, option a is correct.

One of the basic ideas of social justice theories is the existence of unequal status, rights, and opportunities. In public conversation, it might be confusing because various people often interpret it differently. There are some frequent variants, though. In mathematics, an unjust comparison between two numbers or other mathematical expressions is referred to as an inequality. A relationship between two expressions or values that is not equal to each other is known as inequality in mathematics. So inequality emerges from an imbalance. As an illustration, suppose you wish to get a 250 new bicycle. Different types of inequality are indicated by a variety of notations, including:

A less than sign, such as a, denotes that an is greater than b.

Therefore, The  system of inequalities that is represented by the graph is

Answer:

(-8.6)

Step-by-step explanation: If you look at a graph and pinpoint the location of (8,-6) by going up 8 and then going to the left 6. so the point of (8.-6) is in the top left box and if we are reflecting over the x-axis and the y-axis the point will be at the lower right box therefore the answer is (-8.6).

Answer:

350

Step-by-step explanation:

Let "a" represent the number of adult tickets sold and "s" represent the number of student tickets sold. We can set up the following equation to represent the information given:

a + s = 627

s = a - 73

Substituting the second equation into the first equation gives us:

a + (a - 73) = 627

2a - 73 = 627

2a = 700

a = 350

Thus, there were 350 adult tickets sold.

Answer:

500,000 can be written in expanded form in two different ways:

500,000 = 500,000

500,000 = 5 x 100,000 + 0 x 10,000 + 0 x 1,000 + 0 x 100 + 0 x 10 + 0 x 1

In both cases, the expanded form shows the value of each digit in the number. The first way simply lists the number itself, while the second way breaks down the number into its component parts and shows the value of each digit in relation to the place value it holds in the number.

From the given parameters, the area of the triangle is 288m².

How to calculate the area of a triangle?

A triangle is a polygon with three angles, three vertices and three sides whose sum of angles is 180⁰

Let the vertices of the triangle be labelled ABC

/AB/=16m

/BC/=45m

<ABC=127⁰

The given information formed an obtuse angled triangle.

Area of the triangle (A) = [tex]\frac{1}{2}[/tex]ACsinB

Substituting the various values in the formula we have;

A=[tex]\frac{1}{2} *16*45*sin127^{0}[/tex]

simplifying the equation to get;

A=8*45*0.7986

A=287.5088

A=288m²

Therefore, the area of the triangle to the nearest whole number is 288m²

Answer:

The dividend in the synthetic division below is x+2:

     4 | -6 -5 4 -7

     -   --------------

     -   -1 -1 1 -5

     0 | -5 -4 3 -2

     -   --------------

In synthetic division, the numbers in the top row represent the coefficients of the polynomial being divided, and the number in the bottom row represents the value of the dividend. In this case, the dividend is x+2 because it is the only number in the bottom row that is not a result of the division operation

The total addition of numbers is, 53975687481.

What is addition of numbers?

The other three fundamental arithmetic operations are subtraction, multiplication, and division. Addition is one of these four operations. The total sum or value obtained by adding two whole numbers is the result of the addition.

For the given addition first add the digits on 1st place.

7 + 7 + 7 + 7 + 2 + 2 + 2 + 1 + 8 + 7 + 1 = 51

Take 1 as it is and add 5 on the 10th place numbers.

Now add 10th  place numbers,

6 + 6 + 8 + 8 + 2 + 3 + 4 + 4 + 6 + 6 + 5 = 58

Take 8 as it is and add 5 to the 100th place numbers.

Now, 9 + 9 + 9 + 1 + 2 + 4 + 4 + 0 + 7 + 4  + 5= 54

Take 4 as it is and add 5 to the 1000th place numbers.

Now, 4 + 4 + 4 + 7 + 6 + 7 + 7 + 0 + 1 + 2 + 5 = 47

Take 7 as it is and add 4 to the next addition.

Now, 9 + 6 + 7 + 4 + 8 + 3 + 1 + 2 + 4 + 4 = 48

Take 8 as it is and add 4 to the next addition.

Now, 8 + 7 + 7 + 9 + 7 +  2 + 2 + 4 = 46

Take 6 as it is and add 4 to the next addition.

Now, 7 + 6 + 6 + 2 + 6 + 1 + 3 + 4 = 35

Take 5 as it is and add 3 to the next addition.

Now, 4 + 9 + 4 + 3 + 4+ 3  = 27

Take 7 as it is and add 2 to the next addition.

Now, 7 + 4 + 2 + 4 + 2= 19

Take 9 as it is and add 1 to the next addition.

Now, 9 + 3 + 1 = 13

Take 3 as it is and add 1 to the next number.

4 + 1 = 5.

Now take the last numbers one by one from step by step.

The triangles can be proven congruent using the ASA congruence postulate.

Thus, we can say that triangles ABK and CBK are congruent.

Triangles are congruent, according to the Angle Side Angle Postulate (ASA), if any two angles and their included side are equivalent in the triangle. The side between two angles is considered an included side.

Additionally, you can confirm that your two triangles are congruent by employing the Side Angle Side Postulate (SAS). In this case, we choose a side and its equivalent side on two triangles rather than two angles.

Triangles are said to be congruent according to the SAS Postulate if any pair of corresponding sides and their included angle are also congruent.

Answer:

See below

Step-by-step explanation:

The graph that shows the straight line → x - 5y = 27 is plotted and attached.

The general equation of a straight line is -

y = mx + c

where -

[m] is slope of the line.

[c] is the y - intercept of the line.

Given is the equation of the line as -

x - 5y = 27

The given equation of the line is -

x - 5y = 27

Rearranging the equation, we get -

5y = x - 27

y = (1/5)x - (27/5)

y = 0.2x - 5.4

Now, refer to the graph attached. The slope [m] of the equation will be -

m = 0.2 and the [y] - intercept will be y = - 5.4.

Therefore, the graph that shows the linear relation → y = 0.2x - 5.4 is plotted and attached.

An inequality in mathematics is a relationship that makes a non-equal comparison between two numbers or other mathematical expressions. It is most commonly used to compare the sizes of two numbers on a number line.

From given question :

-5x-3.5>6.5

-5x > 10

X > -50

Since, we have to solve for x

so, we will isolate x on anyone side

step-1:

Add both sides by 3.5

- 5x - 3.5 + 3.5 > 6.5 + 3.5

- 5x > 10

step-2:

Divide both sides by -5

we know that whenever we divide both sides by negative sign , it's inequality gets revered

so, we get

- 5x / -5 < - 50 / -5

we get

x < 10

The value of x in the figure having 3 angles on a line as shown in the image attached below is 28.

The angle is formed by two rays and a common point.

To calculate the value of x using the diagram attached below:

∠AOC+∠COD+∠BOD = 180° because the sum of all the angles on a line is 180°

On substituting the values from the figure,

∠AOC=3x-7

∠COD=55

∠BOD=x+20

∠AOC+∠COD+∠BOD =3x-7+55+x+20

3x-7+55+x+20=180

4x+68=180

4x=112

x=28

It takes 11.55 years for money to double if invested at 6% compound interest.

What is compound interest?

Calculating the answer exactly:  P⁰°⁰⁶ⁿ=A .

We don’t know the initial value of the principal but we do know that the accumulated value is double (twice) the principal.

P⁰°⁰⁶ⁿ = 2P

We divide both sides by  P

e⁰°⁰⁶ⁿ = 2

Using natural logarithm:

0.06 n = ln(2)

n = ln(2)/0.06

n = 11.55 years

The equivalent equations of y - 4 = 2/3(x - 1) are y - 4 = 2/3x - 2/3 and y  = 2/3x + 10/3

From the question, we have the following parameters that can be used in our computation:

y - 4 = 2/3(x - 1)

We start by expanding the bracket

So, we have the following representation

y - 4 = 2/3x - 2/3

Next, we add 4 to both sides of the equation

This gives

y - 4 + 4 = 2/3x - 2/3 + 4
