Answer: B(8, -8 )
Step-by-step explanation: The formula for calculating mid - point between two points is given as :
M = ( ,
)
The mid point has been given from the question .
= -2
= ?
= 4
= ?
substituting into the formula , we have
(3 , - 2 ) = ( ,
)
Equating x -component to x and y component to y , we have
3 =
cross multiplying , we have
6 = -2 +
Therefore:
= 8
Also , equating y component to y , we have
-2 =
-4 = 4 +
= -8
Therefore :
= 8
= -8
check
-2 + 8 / 2 = 3 and
-8 + 4 / 2 = -2
Here is the definition of a negative exponent.
For any non-zero value of a,
Look at your problem and follow the definition.
Since 4^3 = 4 * 4 * 4 = 64, we can now write:
