The given system of equation has no solution.

What is system of equations?

Equations simultaneously, or a system of equations Multiple equations in algebra must be solved concurrently (i.e., the solution must satisfy all the equations in the system). There must be an equal number of equations and unknowns for a system to have a singular solution. There is no guarantee of a solution even then.

Consider the given system of equations

4x + 3y = -2

6y = -4 - 8x

It can be written as,

4x + 3y = -2              ...(1)

8x + 6y = -4              ...(2)

Divide equation (2) by 2

⇒ 4x + 3y = -2           ...(3)

Subtract equation (1) and (3)

      4x + 3y = -2

 -    4x + 6y = -4

Answer:

Step-by-step explanation:

In order to find the equation of a line, you must first find the slope and y-intercept point.

Remember, the equation for a line is.

y = mx+b

m = slope

b = y-intercept

To find slope

m = y2-y1/x2-x1

x1 , y1   x2, y2

(-3, 7)   (4, -7)

/ = divided by

Plug those values into slope equation

(-7 - 7)/(4 - (-3))

= -14/7

m = -2

so now we know the slope; -2

y = -2x+b

Now lets find b:

Plug in any point on the line, lets use (-3, 7)

-3 is x

7 is a y

y = mx + b

7 = (-2)(-3) + b

7 - 6 = b

b = 1

So the final equation is  

y = -2x + 1

The number of toy robots on the assembly line that will be approved by the quality-control inspector is 155.904 robots.

Percentage of toy robots on an assembly line approved = 76.8%

Number of toy robots on an assembly line = 203

Number of toy robots on an assembly line approved = Percentage of toy robots on an assembly line approved × Number of toy robots on an assembly line

= 76.8% × 203

= 0.768 × 203

= 155.904 robots.

In conclusion, 155.904 robots will be approved on the assembly line by the quality-control inspector.

The average rate of change for each function over the interval 4 ≤ x ≤ 9 for each function is given as follows:

Hence, the average rate of change of g(x) is three times that of f(x).

The average rate of change of a function is given by the change in the output divided by the change in the input.

The question that would most likely help one understand this excerpt from Adam Smith's book The Wealth of Nations is, "how does self-interest result in societal benefit?"

The main argument of Adam Smith's The Wealth of Nations is that society benefits when each person pursues their own self-interest. He referred to this fulfillment's driving force as the "invisible hand."

"Consumption is the sole purpose of all production," said economist Adam Smith. It implies that the level of consumption affects the production of goods and services.

Adam Smith was one of the first thinkers of his era to assert that wealth is produced through labor that is productive and that people are driven by self-interest to make the best use of their resources. He argued that capital investments generated profits, and that capital is allocated to projects where the greatest profits can be realized.

The amount of the bill is $25

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

Tip amount = $4.50

Tip proportion = 18%

The above parameters means that

Tip amount = Tip proportion * the amount of the bill

Substitute the known values in the above equation, so, we have the following representation

18% * the amount of the bill = 4.50

So, we have

the amount of the bill = 4.50/18%

By takin a quotient, we will see that she can make 4 complete cards in the time she has.

We know that Susan has (1 + 1/2) hours to make cards, and each card takes (1/3) of an hour to make.

To find the total number of cards that Susan can make, we need to take the quotient between the time she has and the time that takes making a single card.

Then we will get:

N = (1 + 1/2)/(1/3)

N = (1 + 1/2)*3

N = 3 + 3/2

N = 3 + 2/2 + 1/2

N = 4 + 1/2

The volume of the rectangular prism is 931.9 cubic meters

The volume of a rectangular prism is calculated by multiplying the length, width, and height of the prism together. For example, if a rectangular prism has a length of 5 cm, width of 3 cm, and height of 2 cm, then the volume of the prism is 5 x 3 x 2 = 30 cm³.

The dimensions given are 12.9ft, 8.6ft, 8.4ft

Volume of prism = length × width × height

volume of prism = 12.9 × 8.6 × 8.4

volume of prism = 931.896 cm³

Volume of prism ≅ 931.9 cm³

The equation of line is y = ( 2/3 )x + 2 where the slope m = 2/3

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P = P ( 3 , 4 )

Let the second point be Q = Q ( -9 , -4 )

Now , the slope of the line is ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( -4 - 4 ) / ( -9 - 3 )

Slope m = -8 / -12

Slope m = 2/3

Now , the equation of line is given by y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

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

On simplifying the equation , we get

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

Adding 4 on both sides of the equation , we get

y = ( 2/3 )x + 2

Therefore , the value of A is y = ( 2/3 )x + 2

Hence , the equation of line is y = ( 2/3 )x + 2

If the perimeter of the rectangle field is 48 yards and the length is 6 yards more than the width , then the length of the field is 15 yards and width is 9 yards .

The Perimeter of the rectangle field is = 48 yards ,

let the width of the rectangle  field be = w yards ,

let the length of the field be = l yards ,

Given that the length is 6 yards more than width ,

So , According to the question  ,

⇒ l = w + 6 ,

the formula for the perimeter of the rectangle is = 2(l + w) ,

substituting the value of l = w + 6 ,

we get ,

2(w+6 + w) = 48 ,

2w + 6 = 24

2w = 18

w = 18/2 = 9 ,

The length of the rectangle is 15 yards, and the width is 9 yards.

The perimeter of a rectangle is given to be 48 yards. This means that the sum of all four sides of the rectangle is equal to 48 yards. We can represent this mathematically as:

P = 2(l + w)

Where P is the perimeter, l is the length and w is the width.

In this case, we are told that the length of the rectangle is 6 yards more than the width, which we can represent mathematically as:

l = w + 6

We can substitute this value of l into our equation to find the width:

P = 2(w + 6 + w)

P = 2(2w + 6)

P = 4w + 12

48 = 4w + 12

36 = 4w

9 = w

We can now use this value of w to find the length:

l = w + 6

l = 9 + 6

l = 15

Therefore, the length of the rectangle is 15 yards, and the width is 9 yards.
