Step-by-step explanation:

-4.7
-8.1 - -3.4= -4.7
-4.7+-3.4=-8.1
Answer:
The coordinates of point B is (8,-4)
Step-by-step explanation:
Midpoint of a line segment: It is the point on the line segment that divides the segment in two congruent segments.
Since it is given that C is the midpoint of Line segment AB.
Mid-point of a segment of end points
and
is, C=
.
As, given the coordinates of A and C are (2,4) and (5,0)
then, we have
,
;
and 
to find the coordinates of
.

Simplify:

⇒ 
to solve for
we have, 
or
or
= -4
so, the values of
and 
Therefore, the coordinates of point B is (8,-4)
For this case we have the following numeric expression:
40,583
What we should do is write the same number in words.
To do this, we must take into account the correct location of each of the digits.
Then we can write the number correctly.
We have then:
40,583 = Forty thousand five hundred eighty-three
Answer:
The number written in words is:
40,583 = Forty thousand five hundred eighty-three
