Find the equation of a straight line which has slope minus 5 by 4 and passing through the point (-1,2).

Answer»

Given :

Slope ( m ) = - 5/4

COORDINATES of points ( X1 , Y1 ) = ( - 1 , 2 )

To Find :

Equation of the straight line

SOLUTION :

Point slope of line is

$\large \implies \boxed{ \boxed{ \sf y - y_1 = m(x - x_1)}}$

Substitute values in formula

$\implies \sf y - 2 = - \frac{5}{4}(x - ( - 1)) \\ \\\implies \sf y - 2 = - \frac{5}{4}(x + 1) \\ \\ \implies \sf y - 2 = \frac{ - 5x}{4} - \frac{5}{4} \\ \\ \implies \sf y = \frac{ - 5x}{4} - \frac{5}{4} + 2 \\ \\ \implies \sf y = \frac{ - 5x}{4} - \frac{5 + 8}{4} \\ \\ \implies \sf y = \frac{ - 5x}{4} - \frac{13}{4} \\ \\ \implies \sf \frac{ 5x}{4} + y +\frac{13}{4} = 0\\ \\ \sf\implies \frac{ 5x + 4y + 13}{4} = 0 \\ \\ \large \implies \boxed{ \boxed{\sf 5x + 4y +13= 0 }}$

20.

The perimeter of rectangle is 60m.the length of the rectangle exceeds it's width by 6m.find length and breadth

Answer»

ANSWER:

Step-by-step explanation:

Perimeter = 60m

Let the Breadth be x

Length = x + 6

p = 2 ( l + B )

60 = 2 ( x + 6 + x )

60 = 2 ( 2x + 6 )

60 / 2 = 2x + 6

30 = 2x + 6

24 = 2x

x = 12

x = 16

Length = 12 + 6 = 18

Breadth = 12

21.

If x+y+z=0 show that x³+y³+z³=2xyz using it find the value of (17)³-(5)³-(12)³

Answer»

Step-by-step explanation:

Given

x+y+z=0

solution-

x³+y³+z³-3xyz=(x+y+z)(x²+y²+z²-xy-yz-zx)

x³+y³+z³-3xyz=0(x²+y²+z²-xy-yz-zx)

anything MULTIPLIED by 0 is 0

x³+y³+z³-3xyz=0

x³+y³+z³=3xyz

hence proved

the VALUE of (17)³-(5)³-(12)³

let's CHECK if a+b+c=0

17+(-5)+(-12)

17-5-12

17-17

0

so,if a+b+c=0 then x³+y³+z³=3xyz

=3*17*5*12

=3060

42.

the ratio of length and breadth of a rectangle is 3:1 ,and it's perimeter is 36 cm . find the length and breadth of rectangle

Answer»

SoluTion :-

Ratio = 3:1

Perimeter = 36 CM

Length = 3x

Breadth = 1x

$\boxed {\sf {\because \ Perimeter \ of \ a \ rectangle =2(l+<klux>B</klux>)}}\\\\\\\sf {\therefore \ 36 \ cm = 2 (3x + 1x)}$

$\sf {\Rightarrow 36 \ cm = 6x + 2x}\\\\\\\sf {\Rightarrow 36 \ cm = 8x}\\\\\\\sf {\Rightarrow x=\frac{36}{8}}\\\\\\\sf {\Rightarrow x = 4.5\ cm}$

Breadth = 1 × 4.5 = 4.5 cm

Length = 3 × 4.5 = 13.5 cm

Verification :-

36 cm = 2 (l + b) cm

36 cm = 2 (4.5 + 13.5) cm

36 cm = 2 (18) cm

36 cm = 36 cm
