What is the Domain and Range in interval or inequality notation! thank you will award brainliest

Solve the system of equations. y= 2x y= x^2 - 15

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4

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?
