8.	The zeroes of x²–2x –8 is: 1.(2,-4) 2.(4,-2) 3.(-2,-2) 4.(-4,-4)
Answer» Answer: $\Large{\underline{\underline{\bf{Option\:2:\:(<klux>4</klux>,-2)}}}}$ Step-by-step explanation: $\Large{\underline{\underline{\bf{Given:}}}}$ p(x) = x² - 2X - 8 $\Large{\underline{\underline{\bf{To\:Find:}}}}$ Zeros of the polynomial $\Large{\underline{\underline{\bf{Solution:}}}}$ → x² - 2x - 8 = 0 → By splitting the middle term method, x² - 4x + 2x - 8 = 0 → Taking the common factors out, x (x - 4) + 2 (x - 4) = 0 (x - 4) (x + 2) = 0 → Either x - 4 = 0 x = 4 → Or x + 2 = 0 x = -2 → Hence the zeros are 4 and -2 $\boxed{\bold{Zeros\:are\:4\:and\:-2}}$ → THEREFORE option 2 is correct. $\Large{\underline{\underline{\bf{Notes:}}}}$ → The zeros of a polynomial can be FOUND out by Using FACTOR theorem $x=\dfrac{-b\pm\sqrt{b^{2}-4ac } }{2a}$ Splitting the middle term Completing the square method

8.

The zeroes of x²–2x –8 is: 1.(2,-4) 2.(4,-2) 3.(-2,-2) 4.(-4,-4)

Answer»

Answer:

$\Large{\underline{\underline{\bf{Option\:2:\:(<klux>4</klux>,-2)}}}}$

Step-by-step explanation:

$\Large{\underline{\underline{\bf{Given:}}}}$

p(x) = x² - 2X - 8

$\Large{\underline{\underline{\bf{To\:Find:}}}}$

Zeros of the polynomial

$\Large{\underline{\underline{\bf{Solution:}}}}$

→ x² - 2x - 8 = 0

→ By splitting the middle term method,

x² - 4x + 2x - 8 = 0

→ Taking the common factors out,

x (x - 4) + 2 (x - 4) = 0

(x - 4) (x + 2) = 0

→ Either

x - 4 = 0

x = 4

→ Or

x + 2 = 0

x = -2

→ Hence the zeros are 4 and -2

$\boxed{\bold{Zeros\:are\:4\:and\:-2}}$

→ THEREFORE option 2 is correct.

$\Large{\underline{\underline{\bf{Notes:}}}}$

→ The zeros of a polynomial can be FOUND out by

Using FACTOR theorem

$x=\dfrac{-b\pm\sqrt{b^{2}-4ac } }{2a}$

Splitting the middle term
Completing the square method

10.	8x+5y=3 4x+7y=2 by using subtution method
Answer» EXPLANATION. EQUATION are:- => 8x + 5y = 3 .... (1) => 4x + 7y = 2 ..... (2) From equation (1) => 8x = 3 - 5y => x = 3 - 5y / 8 .......(1) put the value of Equation (1) in equation (2) we GET, $\bold{ \implies{4 \times \frac{(3 \: - \: 5y)}{8} } + 7y \: = 2}$ $\bold{\implies{ \frac{3 \: - \: 5y}{2} } \: + \: 7y \: = \: 2}$ $\bold{ \implies{3 \: - \: 5y} + 14y \: = \: 4}$ => 9Y = 1 => y = 1/9 put the value of y = 1/9 in equation (1) we get, => x = 3 - 5y / 8 $\bold{ \implies{x \: = \frac{3 \: - \: 5 \times \frac{1}{9} }{8} }}$ => x = 27 - 5 / 9 / 8 => x = 22 / 9 / 8 => x = 22/72 => x = 11 / 36 THEREFORE, value of x = 11/36 and y = 1/9

10.

8x+5y=3 4x+7y=2 by using subtution method

Answer»

EXPLANATION.

EQUATION are:-

=> 8x + 5y = 3 .... (1)

=> 4x + 7y = 2 ..... (2)

From equation (1)

=> 8x = 3 - 5y

=> x = 3 - 5y / 8 .......(1)

put the value of Equation (1) in equation (2)

we GET,

$\bold{ \implies{4 \times \frac{(3 \: - \: 5y)}{8} } + 7y \: = 2}$

$\bold{\implies{ \frac{3 \: - \: 5y}{2} } \: + \: 7y \: = \: 2}$

$\bold{ \implies{3 \: - \: 5y} + 14y \: = \: 4}$

=> 9Y = 1

=> y = 1/9

put the value of y = 1/9 in equation (1)

we get,

=> x = 3 - 5y / 8

$\bold{ \implies{x \: = \frac{3 \: - \: 5 \times \frac{1}{9} }{8} }}$

=> x = 27 - 5 / 9 / 8

=> x = 22 / 9 / 8

=> x = 22/72

=> x = 11 / 36

THEREFORE,

value of x = 11/36 and y = 1/9

in an examination ramesh gets 28 of total marks and failed by 55 , while suresh gets 37% of total marks and gets 17 more then the passing marks .find the total marks and those necessary for passing

Answer»

Answer:

passing marks = 83 total marks = 270

Step-by-step explanation:

Ramesh GETS = 28 marks and failed by 55 marks

means passing marks are => 55+28 = 83

Also Suresh gets 17 more than the passing marks => 83+17 = 100 = 37%

if 37% = 100

then 100% = 100/37×100

=> 270 marks

यदि किसी वस्तु पर बिक्री कर की दर 2% बढ़ जाने से वस्तु का विक्रय मूल्य ₹140 बढ़ जाता है तो वस्तु का अंकित मूल्य करें

Answer»

दिया है :–

• किसी वस्तु पर बिक्री कर की दर 2% बढ़ जाने से वस्तु का विक्रय मूल्य ₹140 बढ़ जाता है ।

ज्ञात करना है :–

• अंकित मूल्य = ?

हल :–

• हम जानते हैं कि –

✯ अंकित मूल्य + (अंकित मूल्य × दर)/100 = विक्रय मूल्य

⇒ अंकित मूल्य (दर + 100)/100 = विक्रय मूल्य _______eq.(1)

• अब प्रश्नानुसार –

⇒ अंकित मूल्य [(दर +2 ) + 100]/100 = विक्रय मूल्य + 140

• अब समीकरण(1) का प्रयोग करने पर –

⇒ अंकित मूल्य [(दर +2) + 100]/100 = अंकित मूल्य (दर + 100)/100+ 140

⇒ अंकित मूल्य [(दर +2) + 100]/100 - अंकित मूल्य (दर + 100)/100= 140

⇒ अंकित मूल्य [{(दर +2) + 100}/100 - (दर + 100)/100]= 140

⇒ अंकित मूल्य [दर +2 + 100 - दर - 100]/100 = 140

⇒ अंकित मूल्य (2)/100 = 140

⇒ अंकित मूल्य (2) = 140 × 100

⇒ अंकित मूल्य (2) = 14000

⇒ अंकित मूल्य = 14000/2

⇒ अंकित मूल्य = 7000

• अतः , वस्तु का अंकित मूल्य 7,000 ₹ है।

Answer» Solution Given that :- Five years ago, Nuri was thrice as OLD as Sonu Three years letters Nuri will be TWICE as old as Sonu Find :- Present AGE of Nuri & Sonu Explanation Let, Present age of Nuri = x years Present age of Sonu = y years A/C to question, (Five years ago, Nuri was thrice as old as Sonu ) ➡ (x -5) = 3 × (y-5) ➡ x - 3y = -15 + 5 ➡ x - 3y = -10 _________(1) Again, (Three years letters Nuri will be twice as old as Sonu) ➡ (x+3) = 2 × (y+3) ➡ x - 2Y = 6 - 3 ➡ x - 2y = 3 __________(2) Subtract equ(1) & equ(2) ➡ -3y + 2y = -10 - 3 ➡ -y = -13 ➡y = 13 Keep value of y in equ(2) ➡ x - 213 = 3 ➡x = 3 + 26 ➡x = 29* Hence Present age of Nuri ( x ) = 29years Present age of Sonu ( y) = 13 years _________________

Five years ago, Nuri was thrice as old as Sonu three years letters Nuri will be twice as old as Sonu how old are nori and Sonu?

Answer»

Solution

Given that :-

Five years ago, Nuri was thrice as OLD as Sonu
Three years letters Nuri will be TWICE as old as Sonu

Find :-

Present AGE of Nuri & Sonu

Explanation

Let,

Present age of Nuri = x years
Present age of Sonu = y years

A/C to question,

(Five years ago, Nuri was thrice as old as Sonu )

➡ (x -5) = 3 × (y-5)

➡ x - 3y = -15 + 5

➡ x - 3y = -10 _________(1)

Again,

(Three years letters Nuri will be twice as old as Sonu)

➡ (x+3) = 2 × (y+3)

➡ x - 2Y = 6 - 3

➡ x - 2y = 3 __________(2)

Subtract equ(1) & equ(2)

➡ -3y + 2y = -10 - 3

➡ -y = -13

➡y = 13

Keep value of y in equ(2)

➡ x - 2*13 = 3

➡x = 3 + 26

➡x = 29

Hence

Present age of Nuri ( x ) = 29years
Present age of Sonu ( y) = 13 years
