Answer:
- points on the boundary line: (0, 10), (20, 0)
- solution points not on the boundary line: (100, 100)
Step-by-step explanation:
We cannot tell from the posted picture whether the boundary line is solid or dashed, so the answer above is split into two parts. If the boundary line is solid (x+2y≥20), all three listed points are in the solution set. If the boundary line is dashed (x+2y>20), only (100, 100) is in the solution set.

EXPLANATION
The given polynomial is
where a=1,b=k, c=30
Let the zeroes of this polynomial be m and n.
Then the sum of roots is
and the product of roots is
The square difference of the zeroes is given by the expression.
From the question, this difference is 169.
This implies that:
We substitute the values of k into the equation and solve for x.
The zeroes are given by;
This isn't a table, but you can easily make it into one.

Answer
x= -3 -> y= -2
x= -1 -> y= -4
x= 3 -> y= -2
Step-by-step explanation:
The lines around the x in the equation is the absolute value symbol.
If you put a positive in, it stays positive.
If you put a negative in, it becomes positive.
Then solve normally.
Good luck!
