Answer:
![12\dfrac 12\%](https://tex.z-dn.net/?f=12%5Cdfrac%2012%5C%25)
Step by step explanation:
![\text{Let it be}~ x\%,\\\\~~~~~72 \cdot x \% = 9\\\\\\\implies 72\cdot \dfrac{x}{100} = 9\\\\\\\implies x = \dfrac{9 \times 100}{72}\\\\\\\implies x = \dfrac{100}{8}\\\\\\\implies x = \dfrac{25}2\\\\\\\implies x = 12 \dfrac 12\\\\\\\text{Hence 9 is}~ 12\dfrac 12\% ~ \text{of}~ 72](https://tex.z-dn.net/?f=%5Ctext%7BLet%20it%20be%7D~%20x%5C%25%2C%5C%5C%5C%5C~~~~~72%20%5Ccdot%20x%20%5C%25%20%3D%209%5C%5C%5C%5C%5C%5C%5Cimplies%2072%5Ccdot%20%5Cdfrac%7Bx%7D%7B100%7D%20%3D%209%5C%5C%5C%5C%5C%5C%5Cimplies%20x%20%3D%20%5Cdfrac%7B9%20%5Ctimes%20100%7D%7B72%7D%5C%5C%5C%5C%5C%5C%5Cimplies%20x%20%3D%20%5Cdfrac%7B100%7D%7B8%7D%5C%5C%5C%5C%5C%5C%5Cimplies%20x%20%3D%20%5Cdfrac%7B25%7D2%5C%5C%5C%5C%5C%5C%5Cimplies%20x%20%3D%2012%20%5Cdfrac%2012%5C%5C%5C%5C%5C%5C%5Ctext%7BHence%209%20is%7D~%2012%5Cdfrac%2012%5C%25%20~%20%5Ctext%7Bof%7D~%2072)
Answer:
(2, 2 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[
(x₁ + x₂ ) ,
(y₁ + y₂ ) ]
Here (x₁, y₁ ) = (A(5, 8) and (x₂, y₂ ) = B(- 1, - 4) , thus
midpoint = [
(5 - 1),
(8 - 4 ) ] = (2, 2 )
