You're a manager in a company that produces rocket ships. Machine A and Machine B both produce cockpits and propulsion systems. Machine A ran for 22 hours and produced 3 cockpits and 5 propulsion systems. Machine B ran for 44 hours and produced 6 cockpits and 10 propulsion systems.Assume both machines produce cockpits at the same rate and both produce propulsion systems at the same rate.Can we use a system of linear equations in two variables to solve for a unique amount of time that it takes each machine to produce a cockpit and to produce a propulsion system?Choose 1 answer:(A) Yes; it takes Machine A and Machine B2 hours to produce a cockpit and 4 hours to produce a propulsion system.(B) Yes; it takes Machine A and Machine B4 hours to produce a cockpit and 2 hours to produce a propulsion system.(C) No; the system has many solutions.(D) No; the system has no solution.
Q. You're a manager in a company that produces rocket ships. Machine A and Machine B both produce cockpits and propulsion systems. Machine A ran for 22 hours and produced 3 cockpits and 5 propulsion systems. Machine B ran for 44 hours and produced 6 cockpits and 10 propulsion systems.Assume both machines produce cockpits at the same rate and both produce propulsion systems at the same rate.Can we use a system of linear equations in two variables to solve for a unique amount of time that it takes each machine to produce a cockpit and to produce a propulsion system?Choose 1 answer:(A) Yes; it takes Machine A and Machine B2 hours to produce a cockpit and 4 hours to produce a propulsion system.(B) Yes; it takes Machine A and Machine B4 hours to produce a cockpit and 2 hours to produce a propulsion system.(C) No; the system has many solutions.(D) No; the system has no solution.
Equation 1: Let's denote the time it takes Machine A to produce a cockpit as x hours and the time it takes to produce a propulsion system as y hours. We can set up two equations based on the information given for Machine A:Equation 1: 3x+5y=22 (since Machine A produced 3 cockpits and 5 propulsion systems in 22 hours).
Equation 2: Similarly, we can set up an equation for Machine B, which ran for 44 hours and produced 6 cockpits and 10 propulsion systems:Equation 2: 6x+10y=44.
System of Equations: Now, we have a system of two linear equations with two variables. To determine if there is a unique solution, we can check if the equations are multiples of each other. If they are, then the system has many solutions (dependent system). If not, then the system has a unique solution (independent system).
Simplifying Equation 2: Let's simplify Equation 2 by dividing all terms by 2 to see if it matches Equation 1:(6x+10y)/2=44/23x+5y=22.This is the same as Equation 1, which means the two equations are multiples of each other.
Unique Solution: Since the two equations are identical after simplification, the system does not have a unique solution. Instead, it has infinitely many solutions because any solution that satisfies one equation will also satisfy the other.
