Answer:
The population is growing by about 1.34% each year1. We ... Looking at these two equations that represent the balance in two different ... We now solve these as a system of equations.
9) inequality: 4+x>13 Solution: x>9
10) x+19 ≥ 8.2 ; x≥-10.8
11) (Sorry I don’t know what the question means by “interpret”) 17+x ≤ 26; Solution: x ≤9
12) 785+x≤1500; Solution: x≤715
