Let point C has coordinates
Consider vectors
![\overrightarrow{AB}=(x_B-x_A,y_B-y_A)=(8-9,6-9)=(-1,-3),\\ \\\overrightarrow{BC}=(x_C-x_B,y_C-y_B)=(x_C-8,y_C-6).](https://tex.z-dn.net/?f=%5Coverrightarrow%7BAB%7D%3D%28x_B-x_A%2Cy_B-y_A%29%3D%288-9%2C6-9%29%3D%28-1%2C-3%29%2C%5C%5C%20%5C%5C%5Coverrightarrow%7BBC%7D%3D%28x_C-x_B%2Cy_C-y_B%29%3D%28x_C-8%2Cy_C-6%29.)
Since the ratio AB to BC is 1:4, you have that
![\dfrac{-1}{x_C-8}=\dfrac{1}{4}\quad \text{and}\quad \dfrac{-3}{y_C-6}=\dfrac{1}{4}.](https://tex.z-dn.net/?f=%5Cdfrac%7B-1%7D%7Bx_C-8%7D%3D%5Cdfrac%7B1%7D%7B4%7D%5Cquad%20%5Ctext%7Band%7D%5Cquad%20%5Cdfrac%7B-3%7D%7By_C-6%7D%3D%5Cdfrac%7B1%7D%7B4%7D.)
Find
and ![y_C:](https://tex.z-dn.net/?f=y_C%3A)
![x_C-8=-4,\\ \\x_C=-4+8=4,\\ \\y_C-6=-3\cdot 4=-12,\\ \\y_C=-12+6=-6.](https://tex.z-dn.net/?f=x_C-8%3D-4%2C%5C%5C%20%5C%5Cx_C%3D-4%2B8%3D4%2C%5C%5C%20%5C%5Cy_C-6%3D-3%5Ccdot%204%3D-12%2C%5C%5C%20%5C%5Cy_C%3D-12%2B6%3D-6.)

Answer: 0.5
Step-by-step explanation:
Android calculator accepts the above question via copy and paste, and gives 0.5
The point of this question is to try to discover whether or not you know what the expression means.
Rewriting it as (8(15-4)/(4×4)) - 5 would show that you know the meaning. You can check that by feeding it into the calculator as well.
