Answer:

x= 0

Step-by-step explanation:

Let's form an equation using the slope of the line.

\boxed{gradient =  \frac{y1 - y2}{x1 - x2} }

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate

Let the gradient of line be m.

m =  \frac{5 - 2}{x - 1}

m =  \frac{3}{x - 1}

The product of the gradients of 2 perpendicular lines is -1.

m(⅓)= -1

m =  - 1 \div  \frac{1}{3}

m= -1 ×3

m= -3

- 3 =  \frac{3}{x - 1}

- 3(x - 1) = 3

x - 1 =  \frac{3}{ - 3}

x - 1 =  - 1

x= -1 +1

x= 0

17x-3y=4 2x-4y=1 the solution to the system of equations is
Burka [1]

ANSWER

x=\frac{13}{62}

and


y= \frac{-9}{62}e have



EXPLANATION




17x-3y=4---(1)


2x-4y=1



Let us make y the subject and call it equation (2)


2x=1+4y


x=\frac{1}{2}+2y--(2)



We put equation (2) in to equation (1)




17(\frac{1}{2}+2y)-3y=4


\frac{17}{2}+34y-3y=4



34y-3y=4- \frac{17}{2}


Simplify to get,



31y= \frac{8-17}{2}



31y= \frac{-9}{2}


Divide both sides by 31,



y= \frac{-9}{2} \div 31



y= \frac{-9}{2} \times \frac{1}{31}




y= \frac{-9}{62}


We put this value in to equation (2) to get,



x=\frac{1}{2}+2\times -\frac{9}{62}




x=\frac{1}{2} -\frac{18}{62}


We collect LCM to obtain,



x=\frac{31-18}{62}



x=\frac{13}{62}
