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:
in this case, x is the amount more he needs to save per month
350=12(x+20)
distribute
350=12x+240
minus 240 both sides
110=12x
divide both sides by 12
9.166666=x
needs to save about $9.17 more per month or 29.17 permonth

Answer:
y + 5 > -2 i.e. option 4.
Step-by-step explanation:
An inequality is shown in the number line by an arrow and we have to identify the inequality from the options given.
It is clear from the given figure that the y variable is plotted and its value is greater than - 7 but not including - 7.
Therefore, option 4 which gives the inequality y + 5 > -2 will be the correct answer.
As it gives y > - 2 - 5 i.e. y > - 7 (Answer)
1)t=S/U=2.4/12=0.2
2)t=S/U=8.4/36=0,23
3)0.23-0.2=0.03
