So you maybe know that

. Now let us try to simplify the expression

Answer:
The inverse matrix is used to solve the system of linear equations. It also tells us the consistent or inconsistent behaviour of the solution of equations.
Step-by-step explanation:
In real life,
- Whereas in programming which is taught at the university, matrices and inverse matrices are used for coding and encrypting messages.
- Matrices are also used in representing the real world data's like the population of people, infant mortality rate, etc.
- They are best representation methods for plotting surveys.
Answer:
x= 60.4
Step-by-step explanation:
y = 60.4
z= 29.6
x= 60.4
By complementary angle rule
Answer:
step number 1 is incorrect.
Step-by-step explanation:
Here is the solution of this equation [2x-31-1=2].
2x-31-1=2
or 2x-31=2+1
or 2x=2+1+31
or 2x= 34
or x=34/2
or x= 17
the answer of this equation is X=17.
Answer:
C
Step-by-step explanation:
x = -1 and -7
