- Height and Weight For a healthy person who is 4 feet 10 inches tall, the recommended minimum weight is about 91 pounds and increases by about 3.6 pounds for each additional inch of height. The recommended maximum weight is about 115 pounds and increases by about 4.5 pounds for each additional inch of height. (a) Let x be the number of inches by which a person’s height exceeds 4 feet 10 inches and let y be the person’s weight (in pounds). Write a system of inequalities that describes the possible values of x and y for a healthy person. (b) Use a graphing utility to graph the system of inequalities from part (a). (c) What is the recommended weight range for a healthy person who is 6 feet tall?arrow_forwardUse a software program or a graphing utility to solve the system of linear equations. 0.2x2.3y+1.4z0.55w=110.63.4x+1.3y1.7z+0.45w=65.40.5x4.9y+1.1z1.6w=166.20.6x+2.8y3.4z+0.3w=189.6arrow_forwardIf a system of linear equations has infinitely many solutions, then the system is called _______.
