Answer» Answer: The Elimination Method This method for solving a pair of simultaneous linear equations reduces one equation to one that has only a single VARIABLE. Once this has been done, the solution is the same as that for when one line was VERTICAL or parallel. This method is KNOWN as the Gaussian elimination method. Example 2. Solve the following pair of simultaneous linear equations: Equation 1: 2x + 3y = 8 Equation 2: 3x + 2y = 7 Step 1: Multiply each equation by a suitable number so that the two equations have the same leading COEFFICIENT. An easy choice is to multiply Equation 1 by 3, the coefficient of x in Equation 2, and multiply Equation 2 by 2, the x coefficient in Equation 1: 3 * (Eqn 1) ---> 3* (2x + 3y = 8)---> 6x + 9y = 24 2 * (Eqn 2) ---> 2 * (3x + 2y = 7)---> 6x + 4Y = 14 Both equations now have the same leading coefficient = 6 Step 2: Subtract the second equation from the first. -(6x + 9y = 24 -(6x + 4y = 14) 5y = 10 Step 3: Solve this new equation for y. y = 10/5 = 2 Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x. We'll use Equation 1. 2x + 3(2) = 8 2x + 6 = 8Subtract 6 from both sides 2x = 2Divide both sides by 2 x = 1 Solution: x = 1, y = 2 or (1,2)..... *Please* *mark* *brainliest* *and* be my *follower* *for* *sure*

X-2y=14 xy:6 find x2+4y2

Answer»

Answer:

The Elimination Method

This method for solving a pair of simultaneous linear equations reduces one equation to one that has only a single VARIABLE. Once this has been done, the solution is the same as that for when one line was VERTICAL or parallel. This method is KNOWN as the Gaussian elimination method.

Example 2.

Solve the following pair of simultaneous linear equations:

Equation 1: 2x + 3y = 8

Equation 2: 3x + 2y = 7

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading COEFFICIENT. An easy choice is to multiply Equation 1 by 3, the coefficient of x in Equation 2, and multiply Equation 2 by 2, the x coefficient in Equation 1:

3 * (Eqn 1) ---> 3* (2x + 3y = 8)---> 6x + 9y = 24 2 * (Eqn 2) ---> 2 * (3x + 2y = 7)---> 6x + 4Y = 14 Both equations now have the same leading coefficient = 6

Step 2: Subtract the second equation from the first.

-(6x + 9y = 24 -(6x + 4y = 14) 5y = 10

Step 3: Solve this new equation for y.

y = 10/5 = 2

Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x. We'll use Equation 1.

2x + 3(2) = 8 2x + 6 = 8Subtract 6 from both sides 2x = 2Divide both sides by 2 x = 1

Solution: x = 1, y = 2 or (1,2).....

27.	DO THIS GUYS TO BE MARKED BRAINLIEST...................range for which the function f(x) = 2x²– log x, for x > 0 decreases, is
Answer» Solution:- The CONDITION in which the value decreases=f'(x)>0 now f'(x)=4x-1/x ×1/ln(1) f'(x)=4x-1/x since we have to find DECREASING condition so, f'(x)<0 {4x^2-1}/x<0 representing it on the NUMBER line it is given previously that x>0,so we can't cosider left of 0 putting a number,1/4,in the given term we get f'(1/4)=(4×1/16-1)/{1/4)}=-3,which is less than 0 similarly putting any number between 0 and 1/2 ,we will get a number<0 hence range is (0,1/2) {hope it helps}.

27.

DO THIS GUYS TO BE MARKED BRAINLIEST...................range for which the function f(x) = 2x²– log x, for x > 0 decreases, is

Answer»

Solution:-

The CONDITION in which the value decreases=f'(x)>0

now

f'(x)=4x-1/x ×1/ln(1)

f'(x)=4x-1/x

since we have to find DECREASING condition

so,

f'(x)<0

{4x^2-1}/x<0

representing it on the NUMBER line

it is given previously that x>0,so we can't cosider left of 0

putting a number,1/4,in the given term we get

f'(1/4)=(4×1/16-1)/{1/4)}=-3,which is less than 0

similarly putting any number between 0 and 1/2 ,we will get a number<0

hence

range is (0,1/2)

{hope it helps}.

A gets 34% marks . B gets 27% marks andhe also fails by 73 marks. Marks required to pass is?

Answer»

Answer:

299

Step-by-step explanation:

Let PASSING MARKS be x and total marks be y

34%of y+17=x

27% of y +73=x

(34/100)× y +17=(27/100)×y + 73

(34y/100)- (27y/100)=73-17

7y/100=56

y=56×100/7=800

34y/100 +17=x

34*800/100. +17=x

x=272+17=299

Answer» Given :- $\rm\:3x+4y=12$ $\rm\:(m+<klux>N</klux>)x+2(m-n)=(5m-<klux>1</klux>)$ To find :- Value of m and n SOLUTION :- The equations is WRITTEN as:- $\rm\:3x+4y-12=0\:.........................(i)$ $\rm\:(m+n)x+2(m-n)y-(5m-1)=0\:......(ii)$ These equations are of the form $\rm\:{a_1}x+{b_1}y+{c_1}=0,$ $\rm\:{a_2}x+{b_2}y+{c_2}=0$ where $\rm\:a_1=3\:,b_1=4\:,c_1=-12$ and $\rm\:a_2=(m+n)\:,b_2=2(m-n)\:,c_1=-(5m-1)$ For infinitely many Solutions,we must have, $\rm\:\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}$ This holds only when, $\rm\:\dfrac{3}{(m+n)}=\dfrac{4}{2(m-n)}=\dfrac{-12}{-(5m-1)}$ $\rm\longrightarrow\:\dfrac{3}{(m+n)}=\dfrac{2}{(m-n)}=\dfrac{12}{(5m-1)}$ $\rm\longrightarrow\:\dfrac{3}{(m+n)}=\dfrac{12}{(5m-1)}\:and\:\:\dfrac{2}{(m-n)}=\dfrac{12}{(5m-1)}$ $\rm\longrightarrow\:\dfrac{1}{(m+n)}=\dfrac{4}{(5m-1)}\:and\:\:\dfrac{1}{(m-n)}=\dfrac{6}{(5m-1)}$ $\rm\longrightarrow\:4(m+n)=(5m-1)\:and\:\:(5m-1)=6(m-n)$ $\rm\longrightarrow\:m-4n=1\:and\:\:m-6n=-1$ $\rm\longrightarrow\:m=5\:and\:\:n=1$ [on solving the above equation] Hence,for infinitely many solutions the value of m is 5 and n is 1.

For what values of m and n the following system of linear equation has infinetly many solution 3x +4y=12 : (m+n)x +2(m-n)y=5m-1

Answer»

Given :-

$\rm\:3x+4y=12$

$\rm\:(m+<klux>N</klux>)x+2(m-n)=(5m-<klux>1</klux>)$

To find :-

Value of m and n

SOLUTION :-

The equations is WRITTEN as:-

$\rm\:3x+4y-12=0\:.........................(i)$

$\rm\:(m+n)x+2(m-n)y-(5m-1)=0\:......(ii)$

These equations are of the form

$\rm\:{a_1}x+{b_1}y+{c_1}=0,$

$\rm\:{a_2}x+{b_2}y+{c_2}=0$

where $\rm\:a_1=3\:,b_1=4\:,c_1=-12$

and $\rm\:a_2=(m+n)\:,b_2=2(m-n)\:,c_1=-(5m-1)$

For infinitely many Solutions,we must have,

$\rm\:\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}$

This holds only when,

$\rm\:\dfrac{3}{(m+n)}=\dfrac{4}{2(m-n)}=\dfrac{-12}{-(5m-1)}$

$\rm\longrightarrow\:\dfrac{3}{(m+n)}=\dfrac{2}{(m-n)}=\dfrac{12}{(5m-1)}$

$\rm\longrightarrow\:\dfrac{3}{(m+n)}=\dfrac{12}{(5m-1)}\:and\:\:\dfrac{2}{(m-n)}=\dfrac{12}{(5m-1)}$

$\rm\longrightarrow\:\dfrac{1}{(m+n)}=\dfrac{4}{(5m-1)}\:and\:\:\dfrac{1}{(m-n)}=\dfrac{6}{(5m-1)}$

$\rm\longrightarrow\:4(m+n)=(5m-1)\:and\:\:(5m-1)=6(m-n)$

$\rm\longrightarrow\:m-4n=1\:and\:\:m-6n=-1$

$\rm\longrightarrow\:m=5\:and\:\:n=1$ [on solving the above equation]

Hence,for infinitely many solutions the value of m is 5 and n is 1.
