the midpoint of kl is m(4.8, -7.8). one endpoint is l(0.6, -5.6). find the coordinates of the other endpoint k.

Vera_Pavlovna [14]

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points }\\\\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&k&(~ x &,& y~) 
% (c,d)
&l&(~ 0.6 &,& -5.6~)
\end{array}\qquad
% coordinates of midpoint 
\left(\cfrac{ x_2 + x_1}{2}\quad ,\quad \cfrac{ y_2 + y_1}{2} \right)$

$\bf \left( \cfrac{0.6+x}{2}~~,~~\cfrac{-5.6+y}{2} \right)~=~\stackrel{midpoint}{(4.8~,~-7.8)}\quad 
\begin{cases}
\cfrac{0.6+x}{2}=4.8\\\\
0.6+x=9.6\\
\boxed{x=9}\\
---------\\
\cfrac{-5.6+y}{2}=-7.8\\\\
-5.6+y=-15.6\\
\boxed{y=10}
\end{cases}$

The cost of 5 tables exceeds the cost of 8 chairs by Rs.150. Write the linear equation in two variables

Levart [38]

Answer:

The linear equation in two variables is 5u - 8v = 150 .

Step-by-step explanation:

As given

The cost of 5 tables exceeds the cost of 8 chairs by Rs150 .

Let us assume that the cost of one table be u .

Let us assume that the cost of one chairs be v .

Than the equation becomes

5u + 150 = 8v

Simplify the above equation

5u - 8v = 150

Therefore the linear equation in two variables is 5u - 8v = 150 .
