Show that ifAB=IandAC=I, then it follows that B=C. Explain how this proves thatthe inverse of the matrix A is unique.
Anna007 [38]

Answer with Step-by-step explanation:

Suppose that a matrix has two inverses B and C

It is given that AB=I and AC=I

We have to prove that Inverse of matrix is unique

It means B=C

We know that

B=BI where I is identity matrix of any order in which number of rows is equal to number of columns of matrix B.

B=B(AC)

B=(BA)C

Using associative property of matrix

A (BC)=(AB)C

B=IC

Using BA=I

We know that C=IC

Therefore, B=C

Hence, Matrix A has unique inverse .

Pete is saving money to buy a used car
Arlecino [84]

Answer:

450 per month

Step-by-step explanation:

5000-1400=3600

3600/8=450

Since Peter already has 1400 dollars saved you can subtract that form the total amount and since he is trying to get the rest in eight months you just divide the difference by eight.

Alona [7]

Answer:

\boxed{- 12 {s}^{2}  + 11st - 2 {t}^{2} }

Step-by-step explanation:

=  > ( - 3s + 2t)(4s - t) \\  \\  =  >  - 3s(4s - t) + 2t(4s - t) \\  \\  =  >  ( ( - 3s) \times 4s )- (( - 3s) \times t) + (2t \times 4s) - (2t \times t) \\  \\  =  >  - 12 {s}^{2}  - ( - 3st) + 8st - 2 {t}^{2}  \\  \\  =  >  -12 {s}^{2}  + 3st + 8st - 2 {t}^{2}  \\  \\  =  >  - 12 {s}^{2}  + 11st - 2 {t}^{2}
