A²÷x-b²÷y=0a²b÷x+b²a÷y=a+b

Answer» \huge \boxed {hello \: friend}


A²/x-b²/y=0---------1

a²b/x+b²a/y=a+B---2

Now from eq. 2,

=> ab(a/x+b/y)=a+b

=> a/x+b/y=a+b/ab ----- x b ( multiplying b)

=> ab/x+b²/y=a+b/a (after = b&b gets cancelled as ONE was in numerator and one was in denominator)

Equating eqs. 1 & 2,

a²/x-b²/y=0

ab/x+b²/y=a+b/a

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

=> a²/x + ab/x= 0 + a+b/a

=> a²+ab/x=a+b/a

=> a(a+b/x)=a+b/a. (a+b & a+b gets cancelled)

=> x=a²

Therefore, x=a² (ans)

ऐस

सुनो! 

दिए गए बहुपद f (x) और g (x) होने दें। 

ATQ, 

जब f (x) और g (x) को (x-2) से विभाजित किया जाता है, तो वे उसी शेष को छोड़ते हैं। 

Ie (x-2) f (x) और g (x) का कारक है। इसका मतलब है कि 2 च का शून्य है (x) और g (x) 

इसलिए कि, 

f (2) = g (2) 

2x + ax² + 3x-5 = x³ + x 4-4x + a 

2 (2) a + a (2) ³ + 3 (2) -5 = 2² + 2²-4 (2) + a 

2 (8) + ए (4) + 6-5 = 8 + 4-8 + ए 

16 + 4 ए + 1 = 4 + ए 

17 + 4 ए = 4 + ए 

4 ए-ए = 4-17 

3 ए = -13 

a = -13/3

प्रतिभा

 P (x) = 2x3 + ax2 + 3x - 5 और q (x) = x3 + x2 - 4x + प्रति

जैसा कि हम शेष प्रमेय द्वारा जानते हैं,

यदि एक बहुपद p (x) को रैखिक बहुपद (x - a) द्वारा विभाजित किया जाता है, तो शेष भाग (a) है

⇒ x - 2 को p (2) से विभाजित करने पर p (x) का अवशेष। इसी प्रकार, x - 2 से विभाजित होने पर q (x) का शेषफल q (2) होता है

⇒ पी (2) = 2 (2) 3 + ए (2) 2 + 3 (2) - 5

⇒ पी (2) = 16 + 4 ए +6 - 5

⇒ पी (2) = 17 + 4 ए

इसी प्रकार, q (2) = (2) 3 + (2) 2 + -4 (2) + a

⇒ q (2) = 8 + 4–8 + ए

⇒ q (2) = 4 + ए

चूँकि वे दोनों एक ही शेष हैं, इसलिए p (2) = q (2)

⇒ 17 + 4 ए = 4 + ए

⇒ 13 = -3 ए

Area : 25a2 – 35a +12. Give possible expressions for the length And breadth of each of the following rectangle in which their areas,are given​

Answer»

Given that the area of the rectangle is of the FORM 25a² -35a+12

To find:

The dimensions of the rectangle

•Factors of the equation would be the LENGTH and BREADTH of the rectangle

Factorizing,

25a²-35a+12=0

→25a²-20a-15a+12=0

→5a(5a-4)-3(5a-4)=0

→(5a-4)(5a-3)=0

→5a-4=0 or 5a-3=0

→a=4/5 or 3/5

The length and breadth COULD be 4/5 UNITS and 3/5 units

A number is increased by 20% and then it is decreased by 30%

Answer»

Answer:

MARK MY ANS AS BRAINLIEST

STEP-by-step explanation:

The answer is 4% .

Let the number be x.

1st step : It is increasedd by 20% .

Amount if increase = (20/100)*x

THerefore,the number now after increase = Previous value+amount increased

=x+(20/100)*x =(120/100) *x

2nd step: The resultant number is again DECREASED by 20% .

Amount decreased= (20/100)*(120/100)*x = 24x/100

The number now = (120/100) x- (24/100)x =96x/100

Now the original number was x and now it is 96x/100.

so net decrease = x-96x/100

Percentage decrease =(net decrease/ original value)* 100

=4%

What is the equation of the line that is parallel to the given line and passes through the point (-4.-6)

Answer»

The question seems to be incomplete but anyway, here is the process to follow to get the desired solution.

What we need to know?

1) The slope of parallel LINES are the same

2) We will need to know what a point-slope formula is

... y - y = m ( x - x )

m = slope

Let's SAY the slope is 2 and we have to write the equation of the line which is parallel and passes through ( -4, -6 )

Now, all we do is substitute this in the point slope formula.

... y - ( -4 ) = 2 ( x - ( -6 ))

... y + 4 = 2 ( x + 6 )

... y + 4 = 2x + 12

... y = 2x + 8

The equation we would get is y = 2x + 8.

As the slope is not provided in the question, I just took an example.

Hope it HELPS! :)

Express 0.5(bar is on 5) +0.67(bar is on 7) in the form of p/q​

Answer»

FIRST we have to express both in the form of p/q:-

  1. 0.5(bar is on 5)
  2. LET x be 0.5555
  3. => x=0.5555
  4. =>10x=5.5555
  5. =>10x-x=5.5555-x
  6. =>9x=5.5555-0.5555
  7. =>9x=5
  8. =>x=5/9

Again,

  1. 0.67(bar is on 7)

FOLLOW the above steps

=>x=61/90

Now,

5/9-61/90

=-11/90

Discuss the continuity of the function f given by f(x) = x3 + x2 - 1.​

Answer»

ANSWER:

f(x) x³ + x² - 1

Let, g(x) be x + 1= 0

therefore, x = -1

f(x)= f(-1)

therefore,

f(-1) = (-1)³ + (-1)² - 1

= -1 + 1 - 1

= 0 - 1

= -1

In this WAY you can continue the process

twice the numerator is 2 more than the denominator if 3 is added to each the numerator and denominator then a fraction is 2 by 3 find the original number.​

Answer»

\mathfrak{\large{\underline{\underline{Answer :-}}}}

The Original Fraction is {\bf{\dfrac{7}{12}}}

\mathfrak{\large{\underline{\underline{Explanation :-}}}}

Given :

TWICE the numerator = 2 more than the Denominator

3 is ADDED to numerator and Denominator = Fraction is \tt{\dfrac{2}{3}}

To Find :

The Original fraction

SOLUTION :

Consider the numerator as x

Denominator = 2x - 2

\green{\boxed{\tt{\red{\frac{x + 3}{(2x - 2) + 3} =  \frac{2}{3}}}}}

\tt{\implies} \: \dfrac{x + 3}{(2x - 2) + 3} =  \dfrac{2}{3}

\tt{\implies} \:3(x + 3) = 2(2x - 2 + 3)

\tt{\implies} \:3x + 9 = 4x - 4+ 6

\tt{\implies} \:3x + 9 = 4x   + 2

\tt{\implies} \:4x - 3x= 9 - 2

\tt{\implies} \:x = 7

\rule{300}{1.5}

Value of 2x - 2

\tt{\implies} \: (7 \times 2) - 2

\tt{\implies} \: 14 - 2

\tt{\implies} \: 12

Numerator = 7

Denominator = 12

Fraction = \boxed{\boxed{\bf{\dfrac{7}{12}}}}

\therefore The Original Fraction is {\bf{\dfrac{7}{12}}}

\rule{300}{1.5}

\mathfrak{\large{\underline{\underline{Verification :-}}}}

Add 3 to the numerator and Denominator to see whether the new fraction formed is \tt{\dfrac{2}{3}}

\tt{\implies} \:  \dfrac{7 + 3}{12 + 3}  =  \dfrac{2}{3}

\tt{\implies} \:  \dfrac{10}{15}  =  \dfrac{2}{3}

Reduce the Fraction

\tt{\implies} \:  \dfrac{10 \div 5}{15 \div 5}  =  \dfrac{2}{3}

\tt{\implies} \:  \dfrac{2}{3}  =  \dfrac{2}{3}

\therefore The Original Fraction is {\bf{\dfrac{7}{12}}}
