1.	Elimination 2x + 5y = 7 and 3x + 2y = 3
Answer» Answer: 2X+ 5Y = 7. (1) 3X+2y = 3. (2) We need to make the coefficient same Hence, Multiply equation (1) by 2 or 3 ( because any of the variables can be made same) Let us take the no. 3 to multiply with equation (1) 3(2x + 5y =7) 6x + 15y = 21. (this Will be equ. 3) Same , coefficient in equation (2). should me made same So, Let us take the no. 2 to make coefficient same ( here we can take only 2 because we are making the coefficient same of variable X) Multiply equation (2) by 2 2(3x + 2y= 3) 6x+4y = 6. (this will be equ. 4) We have made the coefficient same We need to eliminate the variable X as it's coefficient is same . Therefore we will SUBTRACT the equation (3) and (4) Subtract equation (4) from(3) 6x +. 15y = 21 -. 6x +. 4y =. 6 (-). (-) ( Here 6x will be eliminated) Therefore, 11y = 15 y= 15÷11 y= 15/11 We need to find X therefore Substitute y= 15/11 in any equation We will take equation (2) 3x+ 2y= 3 3x + 2× 15/11 =3 3x+ 30/11= 3. ( 2×15/11 = 30/11 ) 3x = 3-30/11 3x= 3/11 X= 3/11÷3 X= 1/11 (X, y)= ( 1/11, 15/11)

1.

Elimination 2x + 5y = 7 and 3x + 2y = 3

Answer»

Answer:

2X+ 5Y = 7. (1)

3X+2y = 3. (2)

We need to make the coefficient same

Hence,

Multiply equation (1) by 2 or 3 ( because any of the variables can be made same)

Let us take the no. 3 to multiply with equation (1)

3(2x + 5y =7)

6x + 15y = 21. (this Will be equ. 3)

Same , coefficient in equation (2). should me made same

So, Let us take the no. 2 to make coefficient same ( here we can take only 2 because we are making the coefficient same of variable X)

Multiply equation (2) by 2

2(3x + 2y= 3)

6x+4y = 6. (this will be equ. 4)

We have made the coefficient same

We need to eliminate the variable X as it's coefficient is same .

Therefore we will SUBTRACT the equation (3) and (4)

Subtract equation (4) from(3)

6x +. 15y = 21

-. 6x +. 4y =. 6

(-). (-)

( Here 6x will be eliminated)

Therefore,

11y = 15

y= 15÷11

y= 15/11

We need to find X

therefore

Substitute y= 15/11 in any equation

We will take equation (2)

3x+ 2y= 3

3x + 2× 15/11 =3

3x+ 30/11= 3. ( 2×15/11 = 30/11 )

3x = 3-30/11

3x= 3/11

X= 3/11÷3

X= 1/11

(X, y)= ( 1/11, 15/11)

Answer» Given : The SUM of the digits of a two digit number is 12. When the digits are interchanged the new number formed is greater than original number by 54.

Answer»

Given :

The SUM of the digits of a two digit number is 12.
When the digits are interchanged the new number formed is greater than original number by 54.

To Find :

The original number

Solution :

Let the digit at the tens PLACE be X.

Let the digit at the units place be y.

Original Number = (10x+y)

Case 1 :

The sum of digits at the tens place and units place is 12.

EQUATION :

$\implies$ $\sf{x+y=12}$

$\sf{x=12-y\:\:\:\:\:(1)}$

Case 2 :

The digits when interchanged of the original number, the new number formed is greater than original number by 54.

Reversed Number = (10y+x)

Equation :

$\implies$ $\sf{10y+x=10x+y+54}$

$\implies$ $\sf{10y-y=10x-x+54}$

$\implies$ $\sf{9y=9x+54}$

$\implies$ $\sf{9y=9(12-y) +54}$

$\implies$ $\sf{9y=108-9y+54}$

$\implies$ $\sf{9y+9y=108+54}$

$\implies$ $\sf{18y=162}$

$\implies$ $\sf{y=\dfrac{162}{18}}$

$\implies$ $\sf{y=9}$

Substitute, y = 9 in equation (1),

$\implies$ $\sf{x=12-y}$

$\implies$ $\sf{x=12-9}$

$\implies$ $\sf{x=3}$

$\large{\boxed{\bold{Ten's\:digit\:=\:x\:=\:3}}}$

$\large{\boxed{\bold{Unit's\:digit\:=\:y\:=\:9}}}$

$\large{\boxed{\bold{\red{Original\:Number\:=\:10x+y=10(3)+9=30+9=39}}}}$

11.

4/9 of a group of students are girls. If there are 17 more boys than girls, How many students are there altogether?

Answer»

Answer:

Alright, so let’s make the information given into equations

b= # of boys

g= # of girls

x= total NUMBER of students = b + g

4/9(b+g)=g which becomes 4/9b + 4/9g = g

4/9b = 5/9g

g= ((4/9)b)/(5/9)

g + 17 = b

Now solve for g

g= b-17

Now set those both equal to each toher

b-17 = (4/9b)/(5/9)

b-17= 0.8b

b-0.8b = 17

b(1–0.8) = 17

b(0.2) = 17

b= 17/0.2

b= 85

Now we know how MANY boys

Solve for girls

g = b-17

g=68

So there are 85 boys and 68 girls!

Answer» AnswEr:- ZEROS of polynomial = -1/3 & 3/2 $\rule{200}{1}$ Here, given polynomial is : ☛ f(x) = 6x² - 3 - 7x = 0 We can find zeros of polynomial by factorization method:- ⇒ 6x² - 3 - 7x = 0 ⇒ 6x² - 7x - 3 = 0 ⇒ 6x² - 9x + 2x - 3 = 0 ⇒ 3x(2x - 3) + 1(2x - 3) = 0 ⇒ (3x + 1)(2x - 3) = 0 ⇒ 3x = -1 or 2x = 3 ⇒ x = -1/3 or x = 3/2 Therefore, $\therefore\underline{\textsf{Zeros of polynomial = {\textbf{-1/3 \& 3/2 }}}}$ $\rule{200}{1}$ Verification:- Here, α = -1/3 β = 3/2 And, Coefficient of x²(a) = 6 Coefficient of x(b) = -7 Constant term(c) = -3 Relationship 1:- ☛ Sum of zeros = -b/a ⇒ -1/3 + 3/2 = -(-7)/6 ⇒ (-2 + 9)/6 = 7/6 ⇒ 7/6 = 7/6 [HENCE VERIFIED!] Relationship 2:- ☛ PRODUCT of zeros = c/a ⇒ -1/3 × 3/2 = -3/6 ⇒ -1/2 = -1/2 [Hence verified!] Therefore, Relation between the zeros and COEFFICIENTS are verified!

Find the zeroes of the following quadratic polynomial and varify the relentonship between the zeroes and the corfficent : f(x)=6x^-3-7x

Answer»

AnswEr:-

ZEROS of polynomial = -1/3 & 3/2

$\rule{200}{1}$

Here, given polynomial is :

☛ f(x) = 6x² - 3 - 7x = 0

We can find zeros of polynomial by factorization method:-

⇒ 6x² - 3 - 7x = 0

⇒ 6x² - 7x - 3 = 0

⇒ 6x² - 9x + 2x - 3 = 0

⇒ 3x(2x - 3) + 1(2x - 3) = 0

⇒ (3x + 1)(2x - 3) = 0

⇒ 3x = -1 or 2x = 3

⇒ x = -1/3 or x = 3/2

Therefore,

$\therefore\underline{\textsf{Zeros of polynomial = {\textbf{-1/3 \& 3/2 }}}}$

$\rule{200}{1}$

Verification:-

Here,

α = -1/3
β = 3/2

And,

Coefficient of x²(a) = 6
Coefficient of x(b) = -7
Constant term(c) = -3

Relationship 1:-

☛ Sum of zeros = -b/a

⇒ -1/3 + 3/2 = -(-7)/6

⇒ (-2 + 9)/6 = 7/6

⇒ 7/6 = 7/6 [HENCE VERIFIED!]

Relationship 2:-

☛ PRODUCT of zeros = c/a

⇒ -1/3 × 3/2 = -3/6

⇒ -1/2 = -1/2 [Hence verified!]

Therefore,

Relation between the zeros and COEFFICIENTS are verified!

Answer» From image we can see That :- → AC = AD = Let x (Given) → DB = Let y → ∠AED = ∠DBE (Given). → AE = 4 unit (Given). → ∆ABc is a Right Angle ∆ . (Given). Solution :- in ∆ABE & ∆AED, we Have :- → ∠AED = ∠DBE , or = ∠ABE (Given). → ∠EAD = ∠BAE (COMMON Angle). HENCE, → ∆AED ≈ ∆ABE ( By AA SIMILARITY.) THEREFORE, → (AD/AE) = (AE/AB) Putting values Now, we get :- → x/4 = 4/(x+y) → x(x+y) = 44 → x(x + y) = 16 . ______________________ So, ☛Area [∆ABC] = (1/2) Base * Height . ☛Area [∆ABC] = (1/2) * AB * AC ☛Area [∆ABC] = (1/2) * (x + y) * x Putting value from above , we get, ☛Area [∆ABC] = (1/2) * 16 = 8unit². (Ans). Hence, Area of ∆ABC will be 8unit².

Answer»

From image we can see That :-

→ AC = AD = Let x (Given)

→ DB = Let y

→ ∠AED = ∠DBE (Given).

→ AE = 4 unit (Given).

→ ∆ABc is a Right Angle ∆ . (Given).

Solution :-

in ∆ABE & ∆AED, we Have :-

→ ∠AED = ∠DBE , or = ∠ABE (Given).

→ ∠EAD = ∠BAE (COMMON Angle).

HENCE,

→ ∆AED ≈ ∆ABE ( By AA SIMILARITY.)

THEREFORE,

→ (AD/AE) = (AE/AB)

Putting values Now, we get :-

→ x/4 = 4/(x+y)

→ x(x+y) = 4*4

→ x(x + y) = 16 .

______________________

So,

☛Area [∆ABC] = (1/2) * Base * Height .

☛Area [∆ABC] = (1/2) * AB * AC

☛Area [∆ABC] = (1/2) * (x + y) * x

Putting value from above , we get,

☛Area [∆ABC] = (1/2) * 16 = 8unit². (Ans).

Hence, Area of ∆ABC will be 8unit².
