Question

4.The value of x isis order these expressions from least to greatest:χ1- xx-1-1 = x

Answer 1

To answer this question we have to evaluate each expression at the given value of x.

Recall that to evaluate an expression we substitute the variable by the given value.

Evaluating each expression at

`x=-(1)/(4)`

we get:

`\begin{gathered} x=-(1)/(4), \\ 1-x=1-(-(1)/(4))=1+(1)/(4), \\ x-1=-(1)/(4)-1=-(1+(1)/(4)), \\ -(1)/(-(1)/(4))=(1)/((1)/(4))=4. \end{gathered}`

Therefore, the numbers ordered from least to greatest are:

`x-1,\text{ x, 1-x, -1/x.}`

Answer:

`x-1,\text{ x, 1-x, -1/x.}`
