Question

Solve |x| < 13 A. {-13, 13} B. {x| -13< x < 13} C. {x|x < -13, x> 13}

Answer 1

Answer:

the solution for x will be given by  {x| -13 < x < 13}

Therefore the correct option is B.

Step-by-step explanation:

i) given that |x| < 13

ii) therefore x < 13 for positive values of x

iii) for negative values of x we have -x < 13

    therefore x > -13

iv) from ii) and iii) above we can conclude that the solution for x will be given by {x| -13 < x < 13}

Therefore the correct option is B.
