Solve forxeandy. x/a=y/b​

Answer»

ANSWER:

x/a + y/b = 2

ay + xb = 2ab----------( 1 )

ax - by = a² - b²---------( 2 )

from-----( 1 ) &-------( 2 )

multiply ( 1 ) by "a" ( 2 ) by "b"

abx + a²y = 2a²b

abx - b²y = ba² - b³

-------------------------------------------------

y(a² + b²) = 2a²b - ba² + b³

y(a² + b²) = a²b + b³

y(a² + b²) = b(a² + b²)

y = b [ put in -----( 1 )]

we GET,

ay + xb = 2ab

a(b) + xb = 2ab

xb = 2ab - ab

x = ab/b

x = a

Find x + y if 2x + y = 7 and 3x + 2y = 12​

Answer»

Answer:

x + y = 5

Step-by-step explanation:

Given equations,

2x + y = 7 ...(i)

3x + 2Y = 12 ...(ii)

now from equation (i) and (ii) ,

3x + 2y - ( 2x + y ) = 12 - 7

3x + 2y - 2x - y = 5

x + y = 5

HENCE, x + y = 5

QUESTION:

Solve the EQUATION:

  • 2x + 3y = 9
  • 3x + 4y = 5

ANSWER:

  • The values of X = - 21

  • The values of y = 17

GIVEN:

  • 2x + 3y = 9

  • 3x + 4y = 5

TO FIND:

  • The values of x and y.

EXPLANATION:

METHOD 1:

2x + 3y = 9------>1

3x + 4y = 5-----> 2

Multiply by 3 on both sides of equation 1.

6x + 9y = 27 -------> 3

Multiply by 2 on both sides of equation 2.

6x + 8y = 10-------> 4

Subtract equation 3 and 4

\sf 6x + 9y = 27  \\  \\ \sf 6x + 8y = 10 \\\sf  ( - )  \ \ ( - ) \   \ \ ( - ) \\  \underline{ \qquad\qquad\qquad}  \\\sf  0  \ + y \  \ \  = 17 \\ \underline{ \qquad\qquad\qquad}

Substitute y = 17 in equation 1

2x + 3(17) = 9

2x = 9 - 51

2x = - 42

x = - 21

HENCE THE VALUE OF X = - 21 AND Y = 17.

VERIFICATION:

Substitute x = - 21 and y = 17 in equation 2

3( - 21) + 4(17) = 5

- 63 + 68 = 5

5 = 5

HENCE VERIFIED.

METHOD 2:

2x + 3y = 9

2x = 9 - 3y

x = (9 - 3y) / 2

Substitute x = (9 - 3y)/2 in 3x + 4y = 5

3((9 - 3y)/2) + 4y = 5

Multiply by two on both sides.

3(9 - 3y) + 8y = 10

27 - 9y + 8y = 10

- y = 10 - 27

y = 17

Substitute y = 17 in 3x + 4y = 5

3x + 4(17) = 5

3x + 68 = 5

3x = 5 - 68

3x = - 63

x = - 21

HENCE THE VALUE OF X = - 21 AND Y = 17.

The difference of an integer x and 9 is - 1. Find the value of x​

Answer»

GIVEN :–

To Find :–

  • Value of x.

Solution :–

Given that,

Difference between x and 9 is –1.

It means,

⟹ x – 9 = –1

We NEED to find the value of x.

So,

⟹ x = 9 – 1

⟹ x = 8

Hence,

The value of x is 8.

Check :–

Given,

⟹ x – 9 = –1 ---------(1)

  • x = 8

Put the value of x in the equation (1).

⟹ 8 – 9 = –1

⟹ –1 = –1

Hence, both the L.H.S. and the R.H.S. are equal.

So, the value of x is 8 is correct.

WritePPF equstionFor robinsonCrusoe and friday​

Answer»

Answer:

Hii

A Robinson Crusoe economy is a simple framework used to study some fundamental issues in economics.[1] It assumes an economy with one consumer, one producer and two goods. The title "Robinson Crusoe" is a reference to the 1719 novel of the same name authored by Daniel Defoe.

As a thought experiment in economics, many international trade economists have found this simplified and idealized version of the story important due to its ability to simplify the complexities of the real world. The implicit assumption is that the study of a one agent economy will provide useful insights into the functioning of a real world economy with many economic agents. This article PERTAINS to the study of consumer behaviour, producer behaviour and equilibrium as a part of MICROECONOMICS. In other fields of economics, the Robinson Crusoe economy framework is used for ESSENTIALLY the same thing. For example, in public finance the Robinson Crusoe economy is used to study the various types of public goods and certain aspects of collective benefits.[2] It is used in growth economics to develop growth models for underdeveloped or developing countries to embark UPON a steady growth path using techniques of SAVINGS and investment.[3]

Answer»

Answer:

1)

GIVEN:

tan 53° . tan 50° . tan 37° . tan 40° = 1

We know that tan and cot are complementary (i.e. sum is equal to 90°)

\tan(90 ^{ \circ} - \theta)  =  \cot \: \theta

\therefore \:  \tan( {90}^{\circ} - {37}^{\circ} )  =  \cot \:  {37}^{\circ}

and

\tan \: ( {90}^{\circ}  -  {50}^{\circ} ) =  \cot \:  {50}^{\circ}

Therefore,

LHS

\tan \:  {37}^{\circ}  \times \cot \:  {37}^{\circ}  \times\tan \:  {50}^{\circ}  \times \cot \:  {50}^{\circ}

We know that tan and cot are reciprocal of each other.

\tan \:  {37}^{\circ} \times \frac{1}{\tan  {37}^{\circ} }  \times \tan {50}^{\circ}  \times  \frac{1}{\tan {50}^{\circ} }

1 \times 1

1

Therefore,

LHS = RHS

2)

Given:

Two points :

(-15,0) and (6,0)

Here,

x_1 = -15

y_1 = 0

x_2 =6

y_2 = 0

\tt \: Distance  \: Formula =  \sqrt{ {(x_2 - x_1)}^{2} +  {(y_2 - y_1)}^{2}  }

Substituting the VALUES , we get :

\tt \: distance =  \sqrt{(6 - ( - 15))^{2}  +  {(0 - 0)}^{2} }

\tt \: distance \:  =  \sqrt{ {21}^{2} }

\tt\therefore \: distance = 21 \: units

3)

Given:

\frac{4 {x}^{2}  + 3 \sqrt{3}x + 7 }{7}  = 0

Cross MULTIPLYING, we get:

4 {x}^{2}  +  3 \sqrt{3} x + 7 = 0

Here,

a = 4

b = 3√3

c = 7

Answer»

Graphically, the pair of equations 7x - y = 5 and 21x - 3y = 10 REPRESENT two lines which are parallel lines.

Explanation:

  • The FIRST equation is 7x - y = 5
  • The second equation is 21x - 3y = 10

  • Multiplying 3 to the first equation, we get
  • 21x - 3y = 15, whose left hand side is SIMILAR to the that of the second equation.

  • The constant part for the equations are different.

  • Thus the lines are parallel to each other.
