In J, K is the midpoint. The coordinates of ) are (2, 2), and the coordinates of Kare (10, 11). What are the coordinates of L?
DiKsa [7]

Answer:

L(18, 20)

Step-by-step explanation:

In JL, K is the midpoint. The coordinates of J are (2, 2), and the

coordinates of K are (10, 11). What are the coordinates of L?

Solution:

If O(x, y) is the midpoint between two points A(x_1,y_1) and B(x_2,y_2). The equation to determine the location of O is given by:

x=\frac{x_1+x_2}{2} \\\\y=\frac{y_1+y_2}{2}

Since JL is a line segment and K is the midpoint. Given the location of J as (2, 2) and K as (10, 11). Let (x_2,y_2) be the coordinate of L. Therefore:

10=\frac{2+x_2}{2} \\\\20=2+x_2\\\\x_2=18

11=\frac{2+y_2}{2} \\\\22=2+y_2\\\\y_2=20

Therefore L = (18, 20)

5/6 – 6/12<br><br>I am lost bc I'm not a math person so pls help me?
vovangra [49]

First, we must find the common denominator (12)            ✵

10/12-6/12            ✵                 ✵                              ✵                              ✵

Now, why 10?                                     ✵                   ✵                      ✵

Because we CAN'T just take the denominator and change it; we must change both the denominator AND the numerator:

✵                                      •          -                                      ○          

4/12                  ✧                             ✩                                  ✶            ✺         ✱  

We can simplify, or reduce, this fraction:                  ✱  ✱

1/3              ✩                              ✦                                        ✤

I hope it helps!
