Consider the linear system below where $h$ and $k$ are real numbers: $x_1 + hx_2 = 2$ $5x_1 + 10x_2 = k$ 1. State the value(s) of $h$ and $k$ that make this system have no solution. 2. State the value(s) of $h$ and $k$ that make this system have a unique solution. 3. State the value(s) of $h$ and $k$ that make this system have infinitely many solutions.

Step 1
Step 1: We write the augmented matrix of the system: $\begin{bmatrix} 1 & h & 2 \\ 5 & 10 & k \end{bmatrix}$ We perform the row operation $R_2 \rightarrow R_2 - 5R_1$: $\begin{bmatrix} 1 & h & 2 \\ 0 & 10 - 5h & k - 10 \end{bmatrix}$ Show more…

For the linear system x1 + 3x2 = 2 3x1 + hx2 = k Find values for h and k such that the system has: a) no solution b) a unique solution c) infinitely many solutions

5. Determine h and k such that the solution set of the system (i) is empty, (ii) contains a unique solution, and (iii) contains infinitely many solutions. a. x1 + 3x2 = k 4x1 + hx2 = 8 b. -2x1 + hx2 = 1 6x1 + kx2 = -2
Supreeta N.
Choose h and k such that the system has (a) no solution, (b) a unique solution, and (c) many solutions. The system has no solutions only when h = 0 and k is any real number. The system has a unique solution when h ≠0 and k is any real number. The system has many solutions when h = 0 and k ≠0. The system has no solutions only when k ≠0 and h is any real number.
