The scale of the map is equal to 250 miles per 1.7 feet. or 250m/1.7ft. set up as a fraction.
Divide 250 by 1.7 to get how many miles are equal to just 1 foot.
250/1.7 = 147.058824 miles per 1 foot
Multiply that times 3.06 feet (the distance between C and D on the map)
147.058824m/1ft x 3.06ft = 450m
The actual distance between City C and City D should be 450 miles.
        
             
        
        
        
When Area of rectangle is constant, then the length x is inversely proportional to the width y of the rectangle.

We know that the area of a rectangle is given by the product of the length and width of the rectangle. 
Area = Length*Width
In this given problem,
The length of the rerectanglctangle is represented by x
and the width of the rectangle is represented by y
If the area of the rectangle is represented by A now.
So by the formula, 
A = x*y
When A is constant then,
x = A/y 

So from the above calculation we can conclude that about relation between length and width that, 
"When Area of rectangle is constant, then the length x is inversely proportional to the width y of the rectangle."

Step-by-step explanation:
8x + 11=2(4x-7) + 25
8x + 11 = 8x - 14 + 25
8x + 11=8x- 14 + 14 +25 + 11
8x-8x + 11 -11 = 14 + 25 + 11
8x-8x =14 + 25 + 11
X = 50

Determine the inverse function

Replace f(x) with y

Swap the positions of x and y

Multiply both sides by -2


Square both sides


Make y the subject

The inverse has been solved. So, we need to replace y with f'(x)

Next, is to determine the interval

Change inequality to 

Hence, the inverse function is:
