Answer:
I believe that the first answer is A and the second answer is c I'm not that smart but I have hope that it's correct
If I'm reading this right, than all 9 angles are acute?
There is a line and a parabola in the graph.
So, we will get the solution set from the point of intersection of both line and parabola.
Notice that the parabola and the line intersecting at two points E(1, 5) and C(-0.5,2).
So, the solution set is E(1, 5) and C(-0.5,2).
