Answer:
Step-by-step explanation:
First off you need to identify the relationship between the 2 widths. The answer to that is 3 feet in real life = 15 inches in scale drawing. This means multiply by 5 and convert feet to inches. All you need to do is apply this to the height. We have 5 feet, if we multiply by 5 we get 25. Then remember it needs to be inches, so the answer is 25 inches.
1) the standar form of the equation is ax+by = c, therefore, for y = -2/3x+5, multiply by 3 the previous equation, and its result is 3y = -2x+15⇒ 3y +2x = 15
the final result is 2x+3y = 15
Answer:

Step-by-step explanation:
The constraints are
The red line represents the function

At 

At 

Two points are 
The blue line represents the function

at 

at 

Two points are 
The other two constraints are
,
. So, the point has to be in the first quadrant
From the graph it can be seen there are two points where the function will be maximum let us check them.




So, the maximum value of the function is
.
Answer:
(4, 5)
Step-by-step explanation:
Calculate the midpoint using the midpoint formula
midpoint = [( + ), ( + ) ]
with (, ) = (1, 2) and (, ) = (7, 8)
midpoint = [(1 + 7), (2 + 8) ]
= (4, 5)
Y=7
X=-3
The following graph
