Question 7 of 47 1 point what is the equation of a line with a slope of 1/2 that passes through the point, (-2,5)? o a. 1/2x+3 o b. y=1/2x+5 o c. y=x+5 o d. y=1/2x+6

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

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?
