Answer: hello your question is disorganized attached below is the question and solution
answer:
1) The system has a unique solution ( x = 0, y = 0 ) ( D )
2) The system has a unique solution ( x = 0, y = 3, z = 3 ) ( D )
Step-by-step explanation:
1 ) ![\left[\begin{array}{ccc}1&0\\0&1\\0&0\end{array}\right] \left[\begin{array}{ccc}0\\0\\0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%5C%5C0%261%5C%5C0%260%5Cend%7Barray%7D%5Cright%5D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0%5C%5C0%5C%5C0%5Cend%7Barray%7D%5Cright%5D)
this matrix is a homogenous since there are three(3) equations and 2 variables
hence the system has a unique solution ( attached below )
2) Attached below
The matrix is a Non-homogenous system since it comprises of three(3) equations and 2 variables
V = ⁴/₃πr³
V = ⁴/₃(3.14)(6)³
V = ⁴/₃(3.14)(216)
V = ⁴/₃(678.24)
V = 904.23cm³
It is equal to 288πcm³.
Answer:
Step-by-step explanation:
x - 5 = 0.1(x +5)
x - 5 = 0.1x + 5*0.1
x -5 = 0.1x + 0.5 {Add 5 to both sides}
x = 0.1x + 0.5 + 5
x = 0.1x + 5.5
x -0.1x = 5.5 {subtract 0.1x from both sides}
0.9x =5.5 {Divide both sides by 0.9}
x = 5.5/0.9
x = 55/9
x = 6 1/9
