Answer:
![A(-\frac{20}{3} ,-\frac{13}{3})](https://tex.z-dn.net/?f=A%28-%5Cfrac%7B20%7D%7B3%7D%20%2C-%5Cfrac%7B13%7D%7B3%7D%29)
Step-by-step explanation:
Point B partitions AC in a 3:4 ratio.
B is located at (4,1) and C is located at (12,5).
Let
be the coordinates of A.
Then ![(\frac{mx_1+nx_2}{m+n}, \frac{my_1+ny_2}{m+n})=(4,1)](https://tex.z-dn.net/?f=%28%5Cfrac%7Bmx_1%2Bnx_2%7D%7Bm%2Bn%7D%2C%20%5Cfrac%7Bmy_1%2Bny_2%7D%7Bm%2Bn%7D%29%3D%284%2C1%29)
But m:n=3:4 implies m=3 and n=4 and ![(x_2=12,y_2=5)](https://tex.z-dn.net/?f=%28x_2%3D12%2Cy_2%3D5%29)
![(\frac{3x_1+4*12}{3+4}, \frac{3y_1+4*5}{3+4})=(4,1)](https://tex.z-dn.net/?f=%28%5Cfrac%7B3x_1%2B4%2A12%7D%7B3%2B4%7D%2C%20%5Cfrac%7B3y_1%2B4%2A5%7D%7B3%2B4%7D%29%3D%284%2C1%29)
![(\frac{3x_1+48}{7}, \frac{3y_1+20}{7})=(4,1)](https://tex.z-dn.net/?f=%28%5Cfrac%7B3x_1%2B48%7D%7B7%7D%2C%20%5Cfrac%7B3y_1%2B20%7D%7B7%7D%29%3D%284%2C1%29)
![\frac{3x_1+48}{7}=4, \frac{3y_1+20}{7}=1](https://tex.z-dn.net/?f=%5Cfrac%7B3x_1%2B48%7D%7B7%7D%3D4%2C%20%5Cfrac%7B3y_1%2B20%7D%7B7%7D%3D1)
![3x_1+48=28, 3y_1+20=7](https://tex.z-dn.net/?f=3x_1%2B48%3D28%2C%203y_1%2B20%3D7)
![3x_1=-20, 3y_1=-13](https://tex.z-dn.net/?f=3x_1%3D-20%2C%203y_1%3D-13)
![x_1=-\frac{20}{3} , y_1=-\frac{13}{3}](https://tex.z-dn.net/?f=x_1%3D-%5Cfrac%7B20%7D%7B3%7D%20%2C%20y_1%3D-%5Cfrac%7B13%7D%7B3%7D)
