Theorem 4.3 Properties of Additive Identity and Additive Inverse Let v be a vector in R", and let c be a scalar. Then the properties below are true. 1. The additive identity is unique. That is, if vu v, then 0 2. The additive inverse of v is unique. That is, if v+u 0, then u-v 3. 0v 4. cO-0 5. If cv = 0, then c 0 or v-0. 6

(1 point) Prove that if X+0 is an eigenvalue of an invertible matrix A, then is an eigenvalue of A! Proof: Suppose v is an eigenvector of eigenvalue then Au=du. Since A is invertible, we can multiply both sides of Au= du by 50 Az = Azj. This implies that . Since 1 + 0 we obtain that Thus – is an eigenvalue of A-? A.D=AU B. A=X co=A D. X-A7 = E. A- F.
