Answer:
The solution to the system of equation is:
Points on a line (x +y =5)
Step-by-step explanation:
We are asked to find the solution of the system of equations as:
x + y ≥ 5
and x + y ≤ 5.
Clearly from the equation we could observe that both the inequalities are similar there is just a change of the sign in the inequality.
one has ≤ sign and the other has ≥ sign.
Hence the common region is:
x + y =5.
Hence, The solution to the system of equation is:
Points on a line (x +y =5)
Hence, the common region will be a straight line with x-intercept at (5,0) and x-intercept of the line at (0,5).

Answer:
9 Model As.
Step-by-step explanation:
Let A represent Press A and let B represent Press B.
So, they own 14 total presses. This means that:
They can print 905 books per day, in other words, since A prints 70 per day and B prints 55 per day:
This is now a system of equations. Solve by substitution. From the first equation, subtract B from both sides:
Substitute this into the second equation: "
First, we can divide everything by 5 to simplify things:
Distribute the left:
Combine like terms:
Subtract 196 from both sides:
Divide both sides by -3
So, the company has 5 Model B presses.
Which means that the company has 14-5 or 9 Model A presses.
And we're done!
