The answer to this problem is y= 1/10x + 60, the y-intercept of the function is $60, and the range is {y| y (less than or equal to) 60}
Answer:
Therefore, we conclute that the map distance between A and C is 35 m.u..
Step-by-step explanation:
We know that the order of three loci is A B C, and the map distance between A and B is 15 m.u., and the map distance between B and C is 20 m.u. We calculate the map distance between A and C.
Therefore, we get

Therefore, we conclute that the map distance between A and C is 35 m.u..
4(x+7)=8x-20
4x+28=8x-20
28=4x-20
48=4x
x=12
