A region R in the xy-plane is given. Find equations for a transformation T that maps a rectangular region S in the uv-plane onto
R, where the sides of S are parallel to the u- and v-axes as shown in the figure below.
R is bounded by y = 2x − 2, y = 2x + 2, y = 2 − x, y = 4 − x
R is bounded by y = 2x − 2, y = 2x + 2, y = 2 − x, y = 4 − x

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!
