Given that the solution set to a system of three linear equations is a line, which of the following is true about the system? a) the system can be either inconsistent or consistent. b) the system can be either independent or dependent. c) the system can only be independent and consistent. d) the system can only be dependent and consistent.

The correct answer is:

d) The system can only be dependent and consistent.

Explanation:

In order for the solution to a system of equations to be a line, this means that the lines must lie on top of one another.  This means they are the same line; the system is consistent since there is at least one solution, and dependent since all of the points in one equation work for the other equations as well.

The correct answer is:

#4 The system can only be dependent and consistent.

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
