39.6-2.35+1.45=38.70
so basically, you are starting at 39.60
then you go down 2.35 and increase by 1.45
so if you do what I did above, you get $38.70.
Answer:
See the graph and explanation below.
Step-by-step explanation:
For this case we have the following function:

We can calculate some points in order to see the tendency of the graph, we can select a set of points for example
and we can calculate the values for f(x) like this
x=-2

x=-1.5

x=-1

x=0

This point correspond to the y intercept.
x=1

x=2

We don't have x intercepts for this case since the functionnever crosses the x axis.
And then we can see the plot on the figure attached.
Answer: Distance from Cleveland to Cincinnati on the second map is 8 km.
Step-by-step explanation:
Since we have given that
The scale on the first map is

That means

Distance from Cleveland to Clncinnati = 40 cm
So,

Similarly, Scale on the second map is given by

So, our 400 km in second map will be

Hence, Distance from Cleveland to Cincinnati on the second map is 8 km.
3.64 is the estimated difference
The new coordinates should be -1, 0. Sorry if I got this wrong.
