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.
First get them all on one side add 7x+60 to both sides 0=x^2+17x+60 now factor what 2 numbers mutltiply to get 60 and add to get 17? 5 and 12 0=(x+5)(x+12) set each to zero
0=x+5 -5=x
0=x+12 -12=x
the factored form is (x+5)(x+12)=0 the solutions are x=-12 and -5
