a.
To find:
The values of m and b for which the given system has exactly one solution.
a.
Answer to Problem 26E
The given system will have exactly one solution, when
Explanation of Solution
Given:
A system of equations:
Calculation:
We know that a system of equations will have exactly one solution, when the slopes of both lines are different.
So the given system will have exactly one solution, when the value of m is other than 3.
Therefore, given system will have exactly one solution, when
b.
To find:
The values of m and b for which the given system has no solution.
b.
Answer to Problem 26E
The given system will have no solution, when
Explanation of Solution
Given:
A system of equations:
Calculation:
We know that a system of equations will have no solution, when the slopes of both lines are same and the y-intercepts are different.
So the given system will have no solution, when the value of m is 3 and the value of b is other than
Therefore, given system will have no solution, when
c.
To find:
The values of m and b for which the given system has infinitely many solutions.
c.
Answer to Problem 26E
The given system will have infinitely many solutions, when
Explanation of Solution
Given:
A system of equations:
Calculation:
We know that a system of equations will have infinitely many solutions, when the slope and y-intercepts of both lines are same.
So the given system will have infinitely many solutions, when the value of m is 3 and the value of b is
Therefore, given system will have infinitely many solutions, when
