Answer:
B) $30.87
Step-by-step explanation:
28.45*0.085=2.41825
When rounded to the nearest cent, you get 2.42.
28.45+2.42=30.87
The total cost after tax is $30.87.
D then A. The first one is D and the second is A. It's all of the numbers combined to make up the domain or range :)
The answer is x=3
So c is 3
Operations that can be applied to a matrix in the process of Gauss Jordan elimination are :
replacing the row with twice that row
replacing a row with the sum of that row and another row
swapping rows
Step-by-step explanation:
Gauss-Jordan Elimination is a matrix based way used to solve linear equations or to find inverse of a matrix.
The elimentary row(or column) operations that can be used are:
1. Swap any two rows(or colums)
2. Add or subtract scalar multiple of one row(column) to another row(column)
as is done in replacing a row with sum of that row and another row.
3. Multiply any row (or column) entirely by a non zero scalar as is done in replacing the row with twice the row, here scalar used = 2
Answer:
2(5+2)
Step-by-step explanation:
The greatest common factor would be 7. So now 35/7 is 5 and 14/7 is 2. Now put it in distributive property! GCF on the outside and the new numbers we just got in the inside. There's your answer! Have a great day! :)
