The minimum and maximum temperature on a cold day in Lollypop Town can be modeled by the equation below: 2|x − 6| + 14 = 38 What

enyata [817]

$2|x-6|+14=38$
$\rightarrow2|x-6|=24$
$\rightarrow|x-6|=12$

There are two cases:
1. $x-6=12\rightarrow x=18$
2. $x-6=-12\rightarrow x=-6$

So the minimum temperature is -6, and the maximum is 18.
