Answer:
R(16,-8)
Step-by-step explanation:
if (x1,y1) and (x2,y2) are coordinates of two points and (x,y) the coordinate of midpoint.
then x=(x1+x2)/2
and y=(y1+y2)/2
let coordinates of R are (x,y)
4=(-8+x)/2
8=-8+x
x=8+8=16
-3=(2+y)/2
-6=2+y
y=-6-2=-8
so R is (16,-8)
Reflection because it shows an exact mirror image of it.
Answer:
The nation has a higher number of productive resources.
Step-by-step explanation:
Low unemployment means that the majority of the people in the nation are working. This can also be seen in the form of a productive resource because people employed are doing some productive work and thus adding to the country's economy.
The first sentence is not true in general. Consider the equation

. There are no solutions. Now consider

. There is only one solution,

.
But whatever. You're asked to demonstrate that

has two solutions (which is true; the right hand side must be a positive integer in order to have two solutions). This follows immediately from the definition of absolute value, which says

So suppose

. Then

Now suppose

. Then

So two solutions to

are

.
