First, find the area of the plot:
25*10=250
1000/250 is 4
the population density is 4 squirrels per square foot.
Answer:
r=0.5
Step-by-step explanation:
0.125r+0.25r-0.0625=0.25+r
0.375r-0.0625=0.25+r
0.375r-r=0.25+0.0625
-0.625r=0.3125
r=0.3125/0.625
r=0.5
18x+9y
9x+y
x+1/9y
2x+4.5y
x+2.25y
Answer:
(a) 
(b) 
(c) Answer of part a is equation of line
which is parallel to y axis and in part by equation of line is
which is parallel to x axis
Step-by-step explanation:
We have given points are 
(a) Equation of line is given x = -9
We have to find the equation of line parallel to x= -9 and passing through 
x = -9 line is parallel to y axis and so slope will be infinite
Equation of line is given by 
So 

(b) Equation of line is given 
This line is parallel to x axis so slope will be zero
So equation of line will be 

(c) Answer of part a is equation of line
which is parallel to y axis and in part by equation of line is
which is parallel to x axis
