Evaluate the following integral using a change of variables. Sketch the original and new regions of integration, R and S. 1 y+2 x-y dxdy Sketch the original region, R, in the xy-plane. Choose the correct graph below. О в. О с. O D. O A. While any changes of variables are correct for this problem use the change of variables that makes the new integral the simplest by making u·x-y and v·y. Sketch the new region, S, in the uv-plane. Choose the correct graph below Ос. O D. O A. Click to select your answer(s) Perform the change of variables and write the new integral in the uv-plane. 1 y+2 (Type exact answers.) Evaluate the integral. 1 y+2 (Type an exact answer. Use integers or fractions for any numbers in the expression.)
