15.	Write an equation in slope-intercept form that goes through the points (5, 2) and (-3, -3).
Answer» Answer:- Given points are (5 , 2) , ( - 3 , - 3). We know that, Equation of a LINE in slope intercept form is : y - y₁ = m(x - x₁) where m is slope of the line and (x₁ , y₁) is the first point. Slope of a line (m) = (y₂ - y₁) / (x₂ - x₁) Let , y₂ = - 3 y₁ = 2 x₂ = - 3 x₁ = 5 So, ⟹ m = ( - 3 - 2) / (- 3 - 5) ⟹ m = - 5 / - 8 ⟹ m = 5/8 Now, REQUIRED equation of the line is : ⟹ y - 2 = (5/8) (x - ( - 3)) ⟹ (y - 2) × 8 = 5 (x + 3) ⟹ 8Y - 16 = 5x + 15 ⟹ 8y - 5x - 16 - 15 = 0 ⟹ 8y - 5x - 31 = 0 ∴ The required equation of the line is 8y - 5x - 31 = 0.

15.

Write an equation in slope-intercept form that goes through the points (5, 2) and (-3, -3).

Answer»

Answer:-

Given points are (5 , 2) , ( - 3 , - 3).

We know that,

Equation of a LINE in slope intercept form is :

y - y₁ = m(x - x₁)

where m is slope of the line and (x₁ , y₁) is the first point.

Slope of a line (m) = (y₂ - y₁) / (x₂ - x₁)

Let ,

y₂ = - 3
y₁ = 2
x₂ = - 3
x₁ = 5

So,

⟹ m = ( - 3 - 2) / (- 3 - 5)

⟹ m = - 5 / - 8

⟹ m = 5/8

Now,

REQUIRED equation of the line is :

⟹ y - 2 = (5/8) (x - ( - 3))

⟹ (y - 2) × 8 = 5 (x + 3)

⟹ 8Y - 16 = 5x + 15

⟹ 8y - 5x - 16 - 15 = 0

⟹ 8y - 5x - 31 = 0

∴ The required equation of the line is 8y - 5x - 31 = 0.

23.	Is the triangle with length of itssides,a=7cm,b=24cm=and=25cm a right- angled triangle
Answer» ☆ Solution ☆ Given :- A = 7cm B = 24 CM C = 25 cm Step-by-Step-Explaination :- As we know that :- In right triangle, the square of the hypotenuse length is equal to the sum the squares of BASE and perpendicular length . Hypotenuse² = Perpendicular² + Base² As given A = 7cm B = 24cm C = 25cm a right angle triangle . As hypotenuse sides is ALWAYS greater length side i.e 25 cm . (25)² = (24)² + (7)² 625 = 576 + 49 625 = 625 THUS the square of the hypotenuse length is equal to the sum the squares of base and perpendicular length . Therefore, A = 7cm B = 24cm C = 25cm is a right angled triangle.

23.

Is the triangle with length of itssides,a=7cm,b=24cm=and=25cm a right- angled triangle

Answer»

☆ Solution ☆

Given :-

A = 7cm
B = 24 CM
C = 25 cm

Step-by-Step-Explaination :-

As we know that :-

In right triangle, the square of the hypotenuse length is equal to the sum the squares of BASE and perpendicular length .

Hypotenuse² = Perpendicular² + Base²

As given

A = 7cm B = 24cm C = 25cm a right angle triangle .

As hypotenuse sides is ALWAYS greater length side i.e 25 cm .

(25)² = (24)² + (7)²

625 = 576 + 49

625 = 625

THUS the square of the hypotenuse length is equal to the sum the squares of base and perpendicular length .

Therefore,

A = 7cm B = 24cm C = 25cm is a right angled triangle.

Answer» To Solve:- $\rm{ \dfrac{x - 1}{x - 2} + \dfrac{x - 3}{x - <klux>4</klux>} = \dfrac{10}{3} }$ Required Answer:- For SOLVING for x, we have to take the LCM i.e. (x - 2)(x -4). Then, ⇒ $\rm{ \dfrac{(x - 1)(x - 4) + (x - 3)(x - 2)}{(x - 2)(x - 4)} = \dfrac{10}{3} }$ Cross multiplying for easier calculation: ⇒ $\rm{3 \{(x - 1)(x - 4) + (x - 3)(x - 2) \}= 10(x - 2)( - 4)}$ Multiplying the terms inside the CURLY brackets: ⇒ $\rm3 {\{ {x}^{2} - 5x + 4 + {x}^{2} - 5x + 6 \} = 10( {x}^{2} - 6x + 8}$ OPENING the parentheses, ⇒ $\rm{3(2 {x}^{2} - 10x + 10) = 10{x}^{2} - 60x + 80}$ ⇒ $\rm{6 {x}^{2} - 30x + 30 = 10 {x}^{2} - 60x + 80}$ Taking 2 as a common from both sides & cancelling it, we have, ⇒ $\rm{3{x}^{2} - 15x+15 = 5{x}^2 - 30x+40}$ Now shifting the terms to one SIDE of the equation: ⇒ $\rm{5{x}^2 - 3{x}^2 - 30x+15x+40 - 15=0}$ ⇒ $\rm{2x^2 -15x+25=0}$ Now find the possible values of x by Middle term factorisation, ⇒ $\rm{2x^2 -10x-5x+25=0}$ ⇒ $\rm{2x(x - 5) -5(x-5) =0}$ ⇒ $\rm{(2x-5)(x-5)=0}$ Equating to 0, We get ⇒ $\rm{x = \dfrac{5}{2} \: or \: 5}$ Hence:- The value of x after solving: 5/2 or 5

3. solve for x and y , x-1 / x-2 + x-3 / x-4 = 10/3.

Answer»

To Solve:-

$\rm{ \dfrac{x - 1}{x - 2} + \dfrac{x - 3}{x - <klux>4</klux>} = \dfrac{10}{3} }$

Required Answer:-

For SOLVING for x, we have to take the LCM i.e. (x - 2)(x -4). Then,

⇒ $\rm{ \dfrac{(x - 1)(x - 4) + (x - 3)(x - 2)}{(x - 2)(x - 4)} = \dfrac{10}{3} }$

Cross multiplying for easier calculation:

⇒ $\rm{3 \{(x - 1)(x - 4) + (x - 3)(x - 2) \}= 10(x - 2)( - 4)}$

Multiplying the terms inside the CURLY brackets:

⇒ $\rm3 {\{ {x}^{2} - 5x + 4 + {x}^{2} - 5x + 6 \} = 10( {x}^{2} - 6x + 8}$

OPENING the parentheses,

⇒ $\rm{3(2 {x}^{2} - 10x + 10) = 10{x}^{2} - 60x + 80}$

⇒ $\rm{6 {x}^{2} - 30x + 30 = 10 {x}^{2} - 60x + 80}$

Taking 2 as a common from both sides & cancelling it, we have,

⇒ $\rm{3{x}^{2} - 15x+15 = 5{x}^2 - 30x+40}$

Now shifting the terms to one SIDE of the equation:

⇒ $\rm{5{x}^2 - 3{x}^2 - 30x+15x+40 - 15=0}$

⇒ $\rm{2x^2 -15x+25=0}$

Now find the possible values of x by Middle term factorisation,

⇒ $\rm{2x^2 -10x-5x+25=0}$

⇒ $\rm{2x(x - 5) -5(x-5) =0}$

⇒ $\rm{(2x-5)(x-5)=0}$

Equating to 0, We get

⇒ $\rm{x = \dfrac{5}{2} \: or \: 5}$

Hence:-

The value of x after solving: 5/2 or 5

a 100 kg mixture of two different types of nuts costa $550. if type A costs $4 per kg and type B costs $7 per kg, how many of each type were used?

Answer»

Given:

A 100 kg mixture of two different types of nuts costa $550.

If type A costs $4 per kg and type B costs $7 per kg

To find:

How many of each type were used?

Solution:

Let's assume,

"x" kg → represents the quantity of type A used

"y" kg → represents the quantity of type B used

The total quantity of the mixture of nuts used = 100 kg

∴ $x + y = 100$ ...... (i)

Type A costs $ 4 per kg, type B costs $ 7 per kg and the total cost of the mixture $ 550

∴ $4x + 7y = 550$ .... (ii)

On multiplying eq. (i) by 4, we get

$4x + 4y = 400$ ..... (iii)

On subtracting eq. (iii) from eq. (ii), we get

$4x + 7y = 550$

$4x + 4y = 400$

- - -

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

$3y = 150$

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

∴ $\bold{y} = \frac{150 }{3} = \bold{50}$ ← type B of nuts

On substituting the VALUE of y in eq. (i), we get

$x + 50 = 100$

$\implies x = 100 - 50$

$\implies \bold{x = 50}$ ← type A of nuts

Thus, 50 kg of each type of nuts were used.

41.	If a transversal intersects two line such that the bisectors of corresponding angels are parallel,then prove that the tow line are parallel
Answer» The transversal AD intersects the two lines PQ and RS at POINTS B and C RESPECTIVELY. BE is the bisector of ∠ABQ and CF is the bisector of ∠BCS. As, BE is the bisector of ∠ABQ, then, ∠ABE= 2/1∠ABQ In the same WAY, ∠BCF= 2/1 ∠BCS Since BE and CF are PARALLEL and AD is the transversal, therefore, by corresponding angle axiom, ∠ABE=∠BCF 2/1∠ABQ= 2/1∠BCS ∠ABQ=∠BCS Therefore, by the converse of corresponding angle axiom, PQ∥RS.

If a transversal intersects two line such that the bisectors of corresponding angels are parallel,then prove that the tow line are parallel

Answer»

The transversal AD intersects the two lines PQ and RS at POINTS B and C RESPECTIVELY. BE is the bisector of ∠ABQ and CF is the bisector of ∠BCS.

As, BE is the bisector of ∠ABQ, then,

∠ABE= 2/1∠ABQ

In the same WAY,

∠BCF= 2/1 ∠BCS

Since BE and CF are PARALLEL and AD is the transversal, therefore, by corresponding angle axiom,

∠ABE=∠BCF

2/1∠ABQ= 2/1∠BCS

∠ABQ=∠BCS

Therefore, by the converse of corresponding angle axiom,

PQ∥RS.
