Answer:
The corresponding point is (5,8)
Step-by-step explanation:
In this problem we know that
The rule of the transformation is equal to
(x,f(x)) ------> (x,f(x)+4)
so
for the point (5,4)
x=5, f(x)=4
substitute
(5,4) ------> (5,4+4)
(5,4) ------> (5,8)
therefore
The corresponding point is (5,8)
 
        
             
        
        
        
Answer:
2. 4a+2c = 5000
4. a + c = 1600
Step-by-step explanation:
 
        
                    
             
        
        
        
So, first, what are the two sides? 
let's call then x and y
we know that 2(x+y)=12.5 (that's the distance around)
so that means that x+y=6.25 (I just divided both by 2)
now, x=4y (from "4 times as long as it is wide")
so we can substitute: 
x+4x=6.25
5x=6.25
x=1.25
so one side, is 1.25 and the other will be 1.25*4=5
and for the area we multiply the two: 
1.25*5=6.25 square kilometers, and this is the answer!
        
                    
             
        
        
        
Answer: The distance around the lot is given by

Step-by-step explanation:
Since we have given that 
Length of rectangular lot is given by

Width of rectangular lot is given by

We need to find the distance around the lot.
As we know the formula for "Perimeter of rectangle":

Hence, the distance around the lot is given by
