Answer:
Step-by-step explanation:
when you have a negative exponent, you are going to have a fraction. Example: 2^4 * 2^-4= 2^4 is 16 2^-4 is 1/16.
You get the 16 but because it was a negative exponent, the 16 goes on the bottom. 16 as a fraction is 16/1.
When you multiply 16/1 and 1/16. It comes up to 16/16 or 1.

Answer:

Step-by-step explanation:
<em>Question is not well formatted; However, the given parameters are</em>
Given
Point = 3/10
A = (-4,-6)
B = (10,7)
Required
Determine the coordinates of the point
Represent the point as ratio

The coordinates can be solved using

Where



Substitute these values in the above formula:





Hence;
The coordinates of the point is 
3.1 x 10 to the tenth power
Explanation:
Divide the negative 16 by 2= -8
Then square -8
So the missing constant is 64
The perfect square would be (x-8)^2
X = -3y + 2
-3y = x - 2
f^-1(x) = y = -(x-2)/3
The inverse here is just a straight line so it is a function.
