SOLUTION: Please check my work Lim x-> 4/7{-} |4-7t|/(14t^2-8t) =lim x-> 4/7{-} 4-7t/(-2t(-7+4)) =lim x-> 4/7{-} -2t =lim x-> 4/7{-} -2(4/7) So, I thought the answer was -8/7/

Algebra ->  Finance -> SOLUTION: Please check my work Lim x-> 4/7{-} |4-7t|/(14t^2-8t) =lim x-> 4/7{-} 4-7t/(-2t(-7+4)) =lim x-> 4/7{-} -2t =lim x-> 4/7{-} -2(4/7) So, I thought the answer was -8/7/      Log On


   



Question 990246: Please check my work
Lim x-> 4/7{-} |4-7t|/(14t^2-8t)
=lim x-> 4/7{-} 4-7t/(-2t(-7+4))
=lim x-> 4/7{-} -2t
=lim x-> 4/7{-} -2(4/7)
So, I thought the answer was -8/7/ This is wrong. Please explain how to solve
Thank you

You can put this solution on YOUR website!
Lim x-> 4/7{-}abs%284-7t%29%2F%2814t%5E2-8t%29
=lim x-> 4/7{-}%284-7t%29%2F%28-2t%28-7%2B4%29%29 Should be: ±%284-7t%29%2F%28-2t%284-7t%29%29
=lim x-> 4/7{-}-2t Should be: ± 1%2F%282t%29
=lim x-> 4/7{-}-2%284%2F7%29 Should be ± 7%2F8
.
You lost the absolute value and moved -2t to the top
