Problems will definitely there because maths is a subject where you will face difficulties ; if you will work on it with keen interest than gradually you will not face difficulty.As per my advice you should 1st solve all doubts of ncert with the optional ones than you should solve sums from practice books i.e. RD Sharma,Navneet etc.... than don't forget to solve last 5 years paper. You can also practice with Gala. I hope it will help you! ??

(Prothom Boss) RS Aggarwal is better than ncert because it gives all questions of ncert

Prothom Bose 5 years, 1 month ago

Maths is not a subject which can be mastered in a day or two.It requires lots of practise.If you realy want to score good in maths than firstly go through all questions in ncert also examples given book(excluding the optional one).Once you are done with ncert and have enough time than solve refresher.But most importantly dont forget to solve the previous years question paper and also go through the latest pattern of exam paper which will be provided by CBSE on ots sites.

Step 1: 2x+3y=9 ..............(eqn 1) 4x-6y=18 ............(eqn 2) divide equation 2 by 2 on both sides, we get: 2x - 3y = 9 2x = 9 + 3y x = (9+ 3y)/2 ..........(eqn 3) step 2: now put the value of x (from equation 3) in equation 1, we get: 2((9+ 3y)/2) + 3y = 9 (9 + 3y) +3y = 9 9 + 6y =9 6y = 9-9 6y = 0 y = 0 .........................(eqn 4) step 3: Now put the value of y = 0 (from equation 4) in equation 3, we get x = (9+ 3(0))/2 x = 9/2 x = 4.5 .......................(eqn 5) so the answer is x = 4.5 and y = 0. step 4: Verification: to verify the answer we can put these values of x and y in any one of the equation 1 or equation 2. put x = 4.5 and y = 0 in equation 1, we get 2x+3y=9 2(4.5) + 3(0) = 9 9 + 0 = 9 9 = 9 L.H.S. = R.H.S.

Gaurav Seth 5 years, 1 month ago

Step 1:

2x+3y=9 ..............(eqn 1)

4x-6y=18 ............(eqn 2)

divide equation 2 by 2 on both sides, we get:

2x - 3y = 9

2x = 9 + 3y

x = (9+ 3y)/2 ..........(eqn 3)

step 2:

now put the value of x (from equation 3) in equation 1, we get:

2((9+ 3y)/2) + 3y = 9

(9 + 3y) +3y = 9

9 + 6y =9

6y = 9-9

6y = 0

y = 0 .........................(eqn 4)

step 3:

Now put the value of y = 0 (from equation 4) in equation 3, we get

x = (9+ 3(0))/2

x = 9/2

x = 4.5 .......................(eqn 5)

so the answer is x = 4.5 and y = 0.

step 4:

Verification:

to verify the answer we can put these values of x and y in any one of the equation 1 or equation 2.

put x = 4.5 and y = 0 in equation 1, we get

2x+3y=9

2(4.5) + 3(0) = 9

9 + 0 = 9

9 = 9

L.H.S. = R.H.S.

It means our answer is right.

Let, O is the centre of the given circle.

A tangent PR has been drawn touching the circle at point P.

Draw QP ⊥ RP at point P, such that point Q lies on the circle.

∠OPR = 90° (radius ⊥ tangent)

Also, ∠QPR = 90° (Given)

∴ ∠OPR = ∠QPR

Now, the above case is possible only when centre O lies on the line QP.

Hence, perpendicular at the point of contact to the tangent to a circle passes through the centre of the circle.

ANSWER

For what value of P, the points (-5,1),(1,p) and (4,-2) are collinear ?

Prove that 3root is a irrational number

Posted by Mayank Gaharwar 5 years, 1 month ago

Yogita Ingle 5 years, 1 month ago

Let us assume to the contrary that √3 is a rational number.

It can be expressed in the form of p/q

where p and q are co-primes and q≠ 0.

⇒ √3 = p/q

⇒ 3 = p²/q² (Squaring on both the sides)

⇒ 3q² = p²………………………………..(1)

It means that 3 divides p²and also 3 divides p because each factor should appear two times for the square to exist.

So we have p = 3r

where r is some integer.

⇒ p² = 9r²………………………………..(2)

from equation (1) and (2)

⇒ 3q² = 9r²

⇒ q² = 3r²

Where q² is multiply of 3 and also q is multiple of 3.

Then p, q have a common factor of 3. This runs contrary to their being co-primes. Consequently, p / q is not a rational number. This demonstrates that √3 is an irrational number.

Show that 5-√3 is irrational

Posted by Anshuman Omm 5 years, 2 months ago

CBSE > Class 10 > Mathematics

1 answers

Yogita Ingle 5 years, 2 months ago

Let us assume that 5 -√3 is rational. Then it can be written in the form

5 - √3 = p/q

or 5 - p/q = √ 3

It implies √3 is a rational number [Since 5 - p/q are rationals

But this contradicts the fact that √3 is irrational. Hence our supposition was wrong. Therefore 5 -√ 3 is irrational.
