Answer:
A) 1:4
Step-by-step explanation:
#We first calculate the campus' area:
#We then calculate the campus' map area in square ft:
Ratio is a comparison between two dimensions:
Hence, the ratio of the area in square miles of the campus to the area in square feet of the map is 1:4
Answer:
any value of x
Step-by-step explanation:
when solved, it comes out to 5x = 5x.
Hope this helps!
Y=5x-7 -3x-2y=-12 (2,3)
y=4x+3 y=-x-2 (-1,-1)
12x+8y=140 5 adults 10 children
12(5)+8(10)=140
60+80=140
Answer:
1. shown below
2.
Step-by-step explanation:
We say exists if the limit remains the same along every path.
Here, f is a function on two variables defined on a disk that contains the point (a,b).
1.
Along y-axis i.e., x = 0:
Along x-axis i.e., y = 0:
As the limit is not the same along different paths, so limit does not exist.
2.
Along the path x = y:
