The coordinates of the vertices of δxyz are (4, –1), (2, –4), and (7, –4). the coordinates of image δxʹyʹzʹ are (−4, −1), (−2, −4), and (−7, −4). this transformation can be expressed as (x, y) ⟶ (−x, y). is δxyz congruent to δxʹyʹzʹ? why or why not?

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?
