Solve this system of equations algebraically using substitution y= x + 4 and x + y=2

Mathematics
1 answer:
barxatty [35]3 years ago
6 0

Answer:

x = -1, y = 3

Step-by-step explanation:

To solve this system of equations, you have to plug in the value of y from the first equation into the second equation:

x + (x + 4) = y

2x + 4 = 2

2x = -2

x = -1

Then, plug x = -1 into one of the equations:

y = (-1) + 4

y = 3

For what value of x is the function g(x)=x/1-x NOT defined?
VMariaS [17]

The function is definately defined at x=0 but not x=1.

But its just one part of the coordinate (x,y).

If the value of y or f(x) is considered, you'll see that it is never possible to attain f(x)=0. In other terms (x,y)= (0,0) is not a defined point in the graph of the function because the graph doesnt pass through that point.

Now I hope you understood what I meant!

Conclusion- The above function is not defined at all points in the space having the abscissa or x=1 in the coordinate and also at ordinate or y=0 in the coordinate.nation:

The average transaction at an automatic teller can be completed in six minutes and customers arrive at the average rate of one e
lorasvet [3.4K]

Answer:

Zero, based on the information provided.

Step-by-step explanation:

The output rate of the teller machine is (1 transaction/6 minutes).  The input rate is (1 customer/10 minutes).  This means that the machine completes a cycle faster than the customers arrive, on the average.  I don't know how an average can be calculated without more information.  If we assume customers arrive every 10 minutes, and no one screws up the machine, that there should be no waiting line.   Is there more information about when the customers arrive?  E.g., 50 arrive in the first hour the machine is open.
