Use factoring to find the zeros of the function, and then use the zeros to determine the vertex of the parabola. State the coordinates of the vertex. 1. y=x^2+2x-63
2. y=x^2+2x-24
3. y=x^2+4x-5
4. y=x^2+9x+18

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
