Answer:
b. The system is not in echelon form because the system is not organized in descending "stair step" pattern so that the index of the leading variables increases from the top to bottom.
Step-by-step explanation:
The given linear system has a equation which is not in echelon form. The echelon is a system which divides the data into rigid hierarchal groups. The given linear equation in not in echelon form as the leading variables are increased from top to bottom indicating descending stair step pattern.
Here is the method for solving that equation:
Step #1: Write the equation:
-15x = 0
Step #2: Divide each side of the equation by -15 :
<u>x = 0</u>
Answer:
The correct equation should be 18 divided by 9=2
Step-by-step explanation:
By dividing the number of muffins by the number of people you get how much each person gets
Ok, so after you do -8a+5a, you also have to do 6 -35, getting the equation
-29-3a
