Question: (100 points) Let / be the interval (-5, co). For u, U E I and a E R define vector addition by u # v

(100 points) Let / be the interval (-5, co). For u, U E I and a E R define vector addition by u # v := uv + 5(u + v) + 20 and scalar multiplication by a Du := (u + 5)" - 5. It can be shown that (), [), [) is a vector sp over R. Find the following: the sum: 2:3 = the scalar multiple: 9 02 = the additive inverse of 2: 82 = the zero vector: Ov = the additive inverse of x
