Answer 2

It looks like you have provided an equation and values for variables B, c, and d. Let's calculate the value of B using the provided values for c and d:

Given: c = {6, -2} d = {1, -2}

The equation is: B = 1/2c - d

First, calculate 1/2c: 1/2c = 1/2 * {6, -2} = {3, -1}

Now, subtract d from 1/2c: B = {3, -1} - {1, -2} = {3 - 1, -1 - (-2)} = {2, 1}

So, B = {2, 1} when c = {6, -2} and d = {1, -2}.
