A. You may set the variables in either order. But for argument sake, let's set as follows:
x = Amount of bookshelves
y = Amount of tables
B. Because of the amount of things you need to make, the following is an inequality using those variables.
x + y > 25
Plus you can determine a second inequality based on the amount of money that you have to spend.
20x + 45y < 675
Finally you may also add in that each value must be greater than or equal to zero, since they cannot have negative tables.
C. By solving the system and looking at basic constraints when graphed, you can see the feasible region has 4 vertices.
(0,0)
(18, 7)
(0, 15)
(33.75, 0) or (33, 0) if you insist on rounding.
Answer:
a
Step-by-step explanation:
Based on the information given, it can be noted that RUTS is a rectangle because the opposite sides are parallel and have equal lengths.
<h3>
Proving the rectangles.</h3>
RU = ST, UT = RS because the opposite sides are parallel and have equal length.
STU and SRU are right angles because they've 90°. Also, URS will be equal to STU. Lastly, USR = SUT because the angles are both alternate angles.

Answer:
x = -3
(-3,7)
Step-by-step explanation:
y = –3x – 2,
y = 7
We know the value of y, y=7
Substitute into the first equation
7 = –3x – 2
Add 2 to each side
7+2 = –3x – 2+2
9 = -3x
Divide each side by -3
9/-3 = -3x/-3
-3 = x
