Prove that if BA=I then BA=AB.

Mathematics
1 answer:
Zanzabum3 years ago
4 0

Answer with Step-by-step explanation:

Since we have given that

BA=I

As we know that

AA⁻¹ = I (A is invertible matrix)

Multiplying A⁻¹ on the both the sides:

BAA^{-1}=IA^{-1}\\\\B=A^{-1}

Using the above result, we get that

BA=I=AA^{-1}\\\\BA=AB

Therefore, BA = AB

Hence, proved.

Brandon made $38.00 in 3 hours. How much would he make in 10 hours
Bad White [126]

Answer:

He would make $126.70 in 10 hours.

Step-by-step explanation:

First, you have to find the unit rate, in other words, how much money he earns in one hour. To do that, you have to divide.

38.00÷3= 12.666667

Once you know how much money Brandon earns in one hour($12.67), you multiply that number by 10.

12.67×10= 126.70

In conclusion, the answer to this solution($126.70) is how much money he earns in 10 hours.
