Answer:
1. All numbers between, including 0 and 15.
Step-by-step explanation:
The domain is the independent variable (x), so in this case, it's be the amount of time James spent typing. James types for 15 minutes, so of course 0 and 15 have to be included, as it'll give a complete graph of what he's done so far.
x = 7
2x + 34 = 4x + 20
2x = 14
504?
