Answer:

False

Step-by-step explanation:

Consider the equations with the same number of equations and variables as shown below,

<u>Case 1</u>

                        x_{1} + x_{2} = 0\\x_{1} + x_{2} = 1

This equation has no solution because it is not possible to have two numbers that give a sum of 0 and 1 simultaneously.

<u>Case 2</u>

                       x_{1} + x_{2} = 1\\2x_{1} + 2x_{2} = 2

This equation has infinitely many possible solutions.

Therefore it is FALSE to say a linear system with the same number of equations and variables, must have a unique solution.

If (-3)^-5=1/x what is the value of x<br><br> Answers:<br><br> -243<br> -1/243<br> 1/243<br> 243
Inga [223]
Solve -3^-5.

Knowing that x^{-1} = \frac{1}{x}, then -3^{-5}= \frac{-1}{243}

That means that x = -243.
