Find the other endpoint given the following Endpoint: (5,-3) Midpoint: (7,-6)

Lilit [14]

The answer is (3, 0) for The second endpoint.

Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.

(Kx + Lx)/2 = Mx

(Kx + 7)/2 = 5

Kx + 7 = 10

Kx = 3

And now we do the same thing for y values

(Ky + Ly)/2 = My

(Ky + -6)/2 = -3

Ky + -6 = -6

Ky = 0

This gives us the final point of (3, 0)

Answer:

B $3x-2y=10$

Step-by-step explanation:

This is correct because when solved it has the same slope as line k.

The slope of k is 3/2.

$3x-2y=10$

first subtract 3x from both sides

$-2y=-3x+10$

next divide both sides by -2

$y=3/2x-5$

this shows that the slope 3/2 is the same as line k

Answer: The value of x =2 units.

Explanation:

Since we have given that

AD= CD

BE= EA

So, we get that D and E are the mid-points of AC and AB respectively.

So, by Mid- point theorem , which states that the line joining the two midpoints is parallel to third side and it is half in length of third side i.e.

$DE=\frac{1}{2}BC$

So, we put the value of DE and BC ,

$5x-3=\frac{1}{2}\times (x+12)\\\\2(5x-3)=x+12\\\\10x-6=x+12\\\\10x-x=12+6\\\\9x=18\\\\x=\frac{18}{9}=2$

Hence, the value of x =2 units.
