We first obtain the equation of the lines bounding R.
For the line with points (0, 0) and (8, 1), the equation is given by:

For the line with points (0, 0) and (1, 8), the equation is given by:

For the line with points (8, 1) and (1, 8), the equation is given by:

The Jacobian determinant is given by

The integrand x - 3y is transformed as 8u + v - 3(u + 8v) = 8u + v - 3u - 24v = 5u - 23v
Therefore, the integration is given by:
18/17 is improper fraction
1 1/17 is mixed
Answer:
Bill = 72
Step-by-step explanation:
Since Bob scored 1/3 of the number of points that Bill would have scored if Bob scored 24 points......
24 divided 1/3
= 72
