The example for an inconsistent system of equations:
x + 2 y = 10 and x + 2 y = 20. If we try to solve it algebraically:
x = 10 - 2 y; 10 - 2 y + 2 y = 20; 10 = 20 ( not true ). We will with something that is not true. Graph of those equations shows 2 parallel lines. Therefore the system is inconsistent.
The system is dependent when we have equivalent equations. For example:
2 x + y = 5 and 4 x + 2 y = 10. If we try to solve this system, we will end up with: 0 = 0 ( true ). The graph of this system shows the same line. This system is dependent.
Finally, if we have just one solution for the system of equations then the system is independent. For example: x + y = 5 and - x + 2 y = 10. When we add those equations: 3 y = 15; y = 15 : 3; y = 5; x + 5 = 5; x = 0. So we have just one solution ( x , y ) = ( 0, 5 ). The system of equations is independent.
201.062, the formula is A=3.14r^2, 8 is your r and then you square it making it 64, then multiply 64 by 3.14 or pi and get 201.06
Answer:
£108.90
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
I would suggest waiting for someone else to respond just to be sure but I am 90% positive that it is C
Length of one card is 3.5 inches
Length of 432 cards is 432*3.5 = 1512 inches
12 inches = 1 foot
1 inch = 1/12 foot
1512 inches = 1512/12 feet = 126
Therefore, the line of baseball cards is 126 feet long
Hope This Helps!
