Chapter E, Problem 1.6EX

To determine

To find the coordinate of X .

Answer to Problem 1.6EX

Option (b) $-2$ , is correct.

Explanation of Solution

Given information: On a number line, point R has coordinate $-5$ and point S has coordinated 3. Point X lies on $\overrightarrow{SR}$ and $SX=5$ .

Options,

  $\begin{array}{l}a.-10.\hfill \\ b.-2.\hfill \\ c.8.\hfill \\ d.0.\hfill \end{array}$

Calculation: The required solutions is obtained as,

It ask for distance so,

  $\begin{array}{l}\left(x\right)+3=5\\ \left(x\right)=2\end{array}$

But it can be possible so it has to be $-2$ .

Therefore, option (b) $-2$ , is correct.
