What are the vertex, focus, and directrix of the parabola with the equation x2+8x+4y+4?

Find the maximum value of p= 4x + 5y subject to the following constraints :

Problem situation: caren is making rice and beans. she can spend no more than $10 on ingredients. she buys one bag of rice for $4.99. beans cost $0.74 per pound. how many pounds of beans, x, can she buy? inequality that represents this situation: 10≥4.99+0.74x drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution.
