Answer:
![9\frac{1}{3}\ mi](https://tex.z-dn.net/?f=9%5Cfrac%7B1%7D%7B3%7D%5C%20mi)
Step-by-step explanation:
we know that
The scale factor is ![\frac{1.5}{2}\ \frac{in}{mi}](https://tex.z-dn.net/?f=%5Cfrac%7B1.5%7D%7B2%7D%5C%20%5Cfrac%7Bin%7D%7Bmi%7D)
That means
1.5 inches on a map represents 2 miles in actual
To convert the dimension on the map to real dimensions, divide by the scale factor
so
![7\ in=7:\frac{1.5}{2}=\frac{14}{1.5}=\frac{28}{3}\ mi](https://tex.z-dn.net/?f=7%5C%20in%3D7%3A%5Cfrac%7B1.5%7D%7B2%7D%3D%5Cfrac%7B14%7D%7B1.5%7D%3D%5Cfrac%7B28%7D%7B3%7D%5C%20mi)
Convert to mixed number
![\frac{28}{3}\ mi=\frac{27}{3}+\frac{1}{3}=9\frac{1}{3}\ mi](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B3%7D%5C%20mi%3D%5Cfrac%7B27%7D%7B3%7D%2B%5Cfrac%7B1%7D%7B3%7D%3D9%5Cfrac%7B1%7D%7B3%7D%5C%20mi)
Answer:
The domain is all the possible inputs for this function. The range is all the possible outputs for this function.
The line starts at the <em>x-value</em> of 0 and ends at the <em>x-value</em> of 12. Therefore, your domain is D: [0, 12].
The line starts at the <em>y-value</em> of 9000 and ends at the <em>y-value</em> of 0. Therefore, your range is R: [0, 9000].
