If 3x - 5y + 2 = Oand 9x + 3y + a = 0 represents the same straight line, find the value of a and b.​

Answer»

SOLUTION

GIVEN

3x - by + 2 = Oand 9x + 3Y + a = 0 represents the same straight line

TO DETERMINE

The value of a and b

EVALUATION

Here it is given that 3x - by + 2 = 0 and 9x + 3y + a = 0 represents the same straight line

So by the given CONDITION

\displaystyle \sf{ \frac{3}{9}  =  \frac{ - b}{3}  =  \frac{2}{a} }

Now

\displaystyle \sf{ \frac{3}{9}  =  \frac{ - b}{3}   \:  \:  \: gives \: }

\displaystyle \sf{ \frac{1}{3}  =  \frac{ - b}{3}   \:  \:  \:  \: }

\displaystyle \sf{  \implies \: b =  - 1 }

Again

\displaystyle \sf{ \frac{3}{9}  = \frac{2}{a}  \:  \:  \: gives}

\displaystyle \sf{ \frac{1}{3}  = \frac{2}{a}  \:  \:  \: }

\displaystyle \sf{ \implies \: a = 6}

FINAL ANSWER

The required value a = 6 , b = - 1

The length of A rectangular field is twice it's breadth. A man jogged around it 5times and covered A distance of 3km. what is the length of field​

Answer»

AnswEr :

Let the BREADTH be x metres and, Length be 2x metres of Rectangluar Field.

Refrence of Image is in the DIAGRAM :

\setlength{\unitlength}{1.5cm}\begin{picture}(8,2)\thicklines\put(7.7,3){\large{A}}\put(7.3,2){\mathsf{\large{x m}}}\put(7.7,1){\large{B}}\put(9.2,0.7){\matsf{\large{2x m}}}\put(11.1,1){\large{C}}\put(8,1){\line(1,0){3}}\put(8,1){\line(0,2){2}}\put(11,1){\line(0,3){2}}\put(8,3){\line(3,0){3}}\put(11.1,3){\large{D}}\end{picture}

\rule{150}{1}

\underline{\bigstar\:\textsf{According to the Question Now :}}

:\implies\tt Distance\:Covered = Perimeter \times Times\: of\:Field\\\\\\:\implies\tt 3 \:Km = 2(Length + Breadth) \times 5\\\\\\:\implies\tt (3 \times 1000) \: m = 2(2x + x) \times 5\\\\\\:\implies\tt 3000 = 2(3x) \times  5\\\\\\:\implies\tt 3000= 6x  \times5\\\\\\:\implies\tt 3000= 30x\\\\\\:\implies\tt \dfrac{3000}{30}=x\\\\\\:\implies\tt x = 100 \:m

\rule{200}{2}

\underline{\bigstar\:\textsf{Length of Rectangluar Field :}}

\longrightarrow\tt Length = 2x\\\\\\\longrightarrow\tt Length =2(100 \:m)\\\\\\\longrightarrow\boxed{\tt Length =200 \:m}

\therefore\:\underline{\textsf{Length of Rectangluar Field is \textbf{200 m.}}}
