Answer: The new solution set is 
Step-by-step explanation: Given that the solution set of a polynomial inequality is (-3, 3).
We are to find the solution set if the inequality symbol is reversed.
Let x denotes the unknown variable in the original inequality.
Then, according to the given information, we can write

Now, if we reverse the sign of the inequality, then the value of x will be

This new solution set can be written as

Thus, the new solution set is 
Answer:
Step-by-step explanation:
y=mx+c
y=1x +(-2)
m=1
c=-2
Call x the number of foreign stamps and y the number of local stamps.
We write equations:
x+y=80
2x/3=y-10
Adding ten to the last equation, we have:
y=2x/3+10
Substituting this for y in the first equation, we have:
5x/3+10=80
Subtracting ten, we have:
5x/3=70
Multiplying by 3/5, we see that x=42, and y=80-42=38, so there are 42 foreign stamps and 38 local stamps.
