Answer

Please see the graph.

Work Step by Step

Red line: $2x+5y \geq 10$ Blue line: $y\geq x^2+1$ We pick the point $(0,0)$ to determine what sides of the graphs to shade. Since both lines have greater than or equal to signs, we will have solid lines. $2x+5y \geq 10$ $2*0+5*0 \geq 10$ $0 + 0 \geq 10$ $0 \geq 10$ (false, so we shade the side of the graph without the point) $y \geq x^2+1$ $0 \geq 0^2+1$ $0 \geq 0 + 1$ $0 \geq 1$ (false, so we shade the side of the graph without the point) The overlap of the two graphs is the solution set to the set of inequalities.
