What is the distance from point E to point D?
2 answers:
Answer:
B
Step-by-step explanation:
Looking at the graph, you can see that points E and D are on the same line. The coordinate for point E is , and the coordinate for point D is
. Because they are on the same line, we only have to look at the y coordinates,
and
. We add these together (ignoring the negative sign in
, because distance can't be negative) to get
, or B.

Answer:
(x,y)=(0,7.333)
Step-by-step explanation:
We are required to:
Maximize p = x + 2y subject to
- x + 3y ≤ 22
- 2x + y ≤ 14
- x ≥ 0, y ≥ 0.
The graph of the lines are plotted and attached below.
From the graph, the vertices of the feasible region are:
- (0,7.333)
- (4,6)
- (0,0)
- (7,0)
At (0,7.333), p=0+2(7.333)=14.666
At (4,6), p=4+2(6)=4+12=16
At (0,0), p=0
At (7,0), p=7+2(0)=7
Since 14.666 is the highest, the maximum point of the feasible region is (0,7.333).
At x=0 and y=7.333, the function p is maximized.
