Plant A can produce 4 sedans and 6 minivans per week. Plant B can produce 5 sedans and 3 minivans per week. How many weeks should each plant operate to produce at least 40 sedans? Express your answer as a linear inequality with appropriate non-negative restrictions and draw its graph. Let x be the number of weeks that plant A is producing vehicles and let y be the number of weeks that plant B is producing vehicles.

Nando is on a rehabilitation program following a car accident. For the first month, he needs to exercise at most five hours per week and must burn at least 2,000 calories per week. The exercise he is allowed to do is brisk walking which burns about 350 calories per hour and biking at a moderate pace which burns about 700 calories per hour. Which graph best represents the set of all points that satisfy the system representing Nando's exercise options? Number of Hours Walking Number of Hours Walking b. 4- of 2- Number of Hours Walking C. 4- Number of Hours Walking d. 3- 2- 0- Number of Hours Walking е. lumber of Hours Biking Number of Hours Biking
