Correct choice is B
Answer:
An identity matrix, is a matrix that have '1' in the main diagonal. All of the other terms are '0'. When you multiply any matrix by the identity matrix, the result is the same matrix that you multiplied.
Example:
![\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%260%5C%5C0%261%260%5C%5C0%260%261%5Cend%7Barray%7D%5Cright%5D)
In the set of the real number is the same that the application of identity property.
Every number multiplied by 1 es the same number.

Answer:
Cost = RM 857143
Loss = RM 107143
Step-by-step explanation:
<u>Given:</u>
- Selling price SP = RM 750000
- Loss% = 12.5
- Cost price CP = x
<u>Cost price is found as:</u>
- SP = CP - 12.5%
- 750000 = x - 12.5%
- 750000= x*(100-12.5)/100
- 750000= 0.875x
- x= 750000/0.875
- x≈ RM 857143
<u>Loss is:</u>
- RM 857143 - 750000 = RM 107143
Answer:
c. 9t+45 that shows distributive property
where it shows a*(b+c)=(a*b)+(b*c).so,9(t+5)=9*t+9*5
