What is the other endpoint if one endpoint is (10,12) and the midpoint is (6,9).?

Lubov Fominskaja [6]

Answer:

$(2,\, 6)$ .

Step-by-step explanation:

Let $(x_{0},\, y_{0})$ and $(x_{1},\, y_{1})$ denote the two endpoints.

The formula for the midpoint of these two points would be:

$\displaystyle \left(\frac{x_{0} + x_{1}}{2},\, \frac{y_{0} + y_{1}}{2}\right)$ .

(Similar to taking the average of each coordinate.)

In this question, it is given that $x_{0} = 10$ whereas $y_{0} = 12$ . Substitute these two values into the expression for the coordinate of the midpoint:

$x$ -coordinate of the midpoint: $\displaystyle \frac{10 + x_{1}}{2} = 6$ .
$y$ -coordinate of the midpoint: $\displaystyle \frac{12 + y_{1}}{2} = 9$ .

Solve these two equations for $x_{1}$ and $y_{1}$ : $x_{1} = 2$ whereas $y_{1} = 6$ .

Hence, the coordinate of the other point would be $(2,\, 6)$ .

What is the result of adding these two equations?<br> 6x + 2y = -2<br> 3x – 2y = -5

Artemon [7]

Answer:

x=-7/9

y = 12/9

Step-by-step explanation:

6x + 2y = -2

3x - 2y = -5

9x = -7 (-2y and +2y eliminated)

x = -7/9

if 3x -2y = -5 then

3 ×(-7/9) -2y =-5➡

-21/9 -2y = -5➡

-2y = -5 + 21/9

-2y = -24/9
