Andrew [12]

Answer:

$6,900

Step-by-step explanation:

Let

x = Amount Monica should earn each month

Rent per month = $2,300

Monica knows that she should spend no more than 1/3 of her income on her rent

1/3 of her Income = rent

1/3 of x = 2,300

1/3x = 2,300

x = 2,300 ÷ 1/3

x = 2,300 * 3/1

x = $6,900

Monica should earn $6,900 each month to afford the rent on her cool new place

Suppose that A is nonsingular. Prove that its inverse A-1 is unique. [Hint: Show that if there exists two matrices, B and C, suc

Bogdan [553]

Answer with Step-by-step explanation:

Let A is non-singular

$\mid A\mid\neq 0$

We have to prove that $A^{-1}$ is unique.

Suppose B and C are inverse of A such that

$BA=I$ and AC=I

By using property $AA^{-1}=A^{-1}A=I$

$C=C$

$(BA)C=B(AC)$

$I\cdot C=B\cdot I$

$C=B$

Hence, the inverse of A is unique.
