so we know that the size of the triangle is decreasing witch means that the scale factor is going to be a fraction. to find this fraction you are going to divide the smaller side by the corisponding longer side.
12/72= 1/6
the correct answer is c 1/6
Break it down and solve parts of it
1800-4+522

Answer:
The points are (-16,7),(10,7),(-3,-6) and (-3,20)
Step-by-step explanation:
We have that one endpoint is at (-3,7) and the length is 13 units.
A point that is 13 units horizontally to the left and right will have the same y-coordinate but with x-coordinates that are 13 units from -3.
![| - 3 - x| = 13](https://tex.z-dn.net/?f=%20%7C%20-%203%20-%20x%7C%20%20%3D%2013)
![( - 3 - x) = 13 \: or \: - ( - 3 - x) = 13](https://tex.z-dn.net/?f=%28%20-%203%20-%20x%29%20%3D%2013%20%5C%3A%20or%20%5C%3A%20%20-%20%28%20-%203%20-%20x%29%20%3D%2013)
![x = - 16 \: or \: x = 10](https://tex.z-dn.net/?f=x%20%3D%20%20-%2016%20%5C%3A%20or%20%5C%3A%20x%20%3D%2010)
Hence we have (-16,7) and (10,7)
Also a point that is 13 units vertically up and down will have the same x-coordinate but with y-coordinates that are 13 units from 7.
![|y - 7| = 13](https://tex.z-dn.net/?f=%20%7Cy%20%20-%207%7C%20%20%3D%2013)
![(y - 7) = 13 \: or \: - (y - 7) = 13](https://tex.z-dn.net/?f=%28y%20-%207%29%20%3D%2013%20%5C%3A%20or%20%5C%3A%20%20-%20%28y%20-%207%29%20%3D%2013)
![y= - 6 \: or \: y = 20](https://tex.z-dn.net/?f=y%3D%20%20-%206%20%5C%3A%20or%20%5C%3A%20y%20%3D%2020)
Hence we again have (-3,-6) and (-3,20)
Answer:
489.5 + m = 756.80 (the amount elias has, added to marks is equal to the total
(756.8- 489.5 = 267.30 which is the amount mark has.)
m= 267.3
the last option is the correct option
