Answer:
1. zeros are -2 and 1
2. zeros are -1 and 3
3. zeros are -3 and 1
4. zeros are -1
5. no zeros
6. no zeros
Step-by-step explanation:
Zeros are points on the graph that are x-intercepts; in the graph we can see that they cross -2 and 1 on the 1st equation, -1 and 3 on the 2nd equation, -3 and 1 in the 3rd equation, and -1 in the 4th equation. Since it intersects no x-intercepts in the 5th and 6th equation, it has no zeros.
You have five numbers 
Among them there is one negative number
this number is smallest.
Note that

Since 6.25>6, then
and these numbers are less than 3
Note that
then
and these numbers are greater than 3.
Therefore, the correct order from the smallest to the greatest is:

4x+2y<=16
3x+3y<=15
2x+y<=8
x+y<=5
3x+2y->maximize profit
X Y profit
1 4 11
2 3 12
3 2 13
4 0 12
3 1 11
3 2 13
2 3 12
1 4 11
0 5 10
