4.angle between 2 straight linesShow that straight lines form isosceles triangle4x - 3y -18 = 0, 3x-4y +16= 0, x + y - 2 = 0

Answer»

Answer:

y^2 + xy - 12x^2 = 0y

2

+xy−12x

2

=0

\Rightarrow y^2 + 4xy - 3xy - 12y^2 = 0⇒y

2

+4xy−3xy−12y

2

=0

\Rightarrow y(y + 4x) - 3x(y + 4x) = 0⇒y(y+4x)−3x(y+4x)=0

\Rightarrow (y + 4x)(y - 3x) = 0⇒(y+4x)(y−3x)=0

So, y = 3xy=3x or y = -4xy=−4x are the two straight lines REPRESENTED by the given equation.

We consider two cases, the first being when y = 3xy=3x is common to both.

Then, we get ax^2 + 2hx(3x) + B(3x)^2 = 0ax

+2hx(3x)+b(3x)

2

=0

i.e. ax^2 + 6hx^2 + 9bx^2 = 0ax

2

+6hx

2

+9bx

2

=0

a = -6h - 9b = -3(2h + 3b)a=−6h−9b=−3(2h+3b)

The second CASE being line y = -4xy=−4x is common to both, which gives

ax^2 + 2hx (-4x) + b(-4x)^2 = 0ax

2

+2hx(−4x)+b(−4x)

2

i.e. ax^2 - 8hx^2 + 16bx^2 = 0ax

a = 8h - 16b = 8(h - 2b)a=8h−16b=8(h−2b)

Step-by-step explanation:

first take the LCM.

Here, lcm = 20.

therefore,

$- \frac{2}{5} \times \frac{4}{4} = - \frac{8}{20}$

$\frac{1}{4} \times \frac{5}{5} = \frac{5}{20}$

Then add the numbers

17. A shopkeeper offers his customers 10% discount and still cars a profit of 25%. What isthe actual cost of the article marked at rs 500?

Answer»

Answer:

Discount GIVEN = 10%

So, selling price = 500 - 500*10%

= 500 - (500*10)/100

= 500 - (5*10)

= 500 - 50

= 450

Now, shopkeeper EARNS a profit of 25%

Let cost price is x

Now x + x*25% = 450

=> x + 25x/100 = 450

=> x + x/4 = 450

=> (4x + x)/4 = 450

=> 5x/4 = 450

=> 5x = 450*4

=> x = (450*4)/5

=> x = 90*4

=> x = 360

So, the actual cost of the article is RS. 360
