The set R2 with vector addition defined by (a comma b )circled plus (c comma d )space equals space (a plus c minus 4 comma space b plus d plus 5 )and scalar multiplication defined by k circled dot (a comma b )space equals space (k a minus 4 k plus 4 comma space k b plus 5 k minus 5 )is a vector space with (4, -5) as the additive identity. What is the additive inverse of (12, -15)?

Andrea's Expression: (1 - 0.2)^w

w: number of weeks

0.2: percent decrease

1 - 0.2: decay factor for each week

I got Eric's Expression wrong :(
