For me, I use proportion to solve this kind of problems.
Not that 1 inch = 100 miles; set up your proportion:
1 inch = 100 miles
------------- -----------
4.7 inches = x miles
*Cross, multiple and divide: 4.7 x 100 / 1 which equals 470 miles.
The actual distance between the two cities is 470 miles.
Answer:
Domain: (-∞, ∞), Range: [-3, ∞)
Step-by-step explanation:
Domain is all of the possible x-values in a solution set, in this case since the solution extends infinitely horizontally it would be:
(-∞, ∞)
The range is just all of the possible y-values in a solution set, which in this set starts from -3 and proceeds on infinitely, making the range:
[-3, ∞)
