Question

Add the following -19/18 and -11/12​

Answer 1

Answer:

the sum of this two is -71/36

Answer 2

Answer:

From the figure, we know that;

D is the midpoint of AB.

E is the midpoint of AC.

F is the midpoint of BC.

In triangle ABC,

Coordinates of A (1, -4)

Coordinates of D (2, -1)

Coordinates of E (0, -12)

We need to find the Coordinates of F which is a midpoint of BC.

Let the Coordinates of B be (x2,y2), C be (x3,y3), and F be (x,y).

Now, using midpoint formula, we will try to find the coordinates of B

Coordinates of B =1+x22=2 and −4+y22=−1

After solving above equation, we get;

Coordinates of B (3, 2)

Now, using midpoint formula, we will try to find the coordinates of C

Coordinates of C =1+x32=0 and −4+y32=−12

After solving above equation, we get;

Coordinates of C (-1, -20)

Now, using midpoint formula, we will try to find the coordinates of F

Coordinates of F =x2+x32=x and y2+y32=y

Putting the values in the above equations, we get;

=3−12=x and 2−202=y

After solving above equation, we get;

Coordinates of F (1, -5) comes on Start I am free ------
