Question 1089046: This is Colby Spence which email is Colbyspence@ymail.com. I having a hard time figuring out the problem ; the optimal operating temperature of a given car engine is 10 degress F of 230 degress F. Write an absolute valuer inerquality for the range of acceptable tempoeratures and solve inequality

abs%28t-230%29%3C=10 where t= temperature of the engine in degrees Fahrenheit says that the difference between the temperature of the engine and 230 should be no more than 10 degrees Fahrenheit.

abs%28t-230%29%3C=10 means that
either 0%3C=t-230%3C=10 ,
or
0%3C-%28t-230%29%3C=10 , which is equivalent to
0%3Et-230%3E=-10 and to -10%3C=t-230%3C0 .
The two inequalities can be written together as
-10%3C=t-230%3C=10 .
Adding 230 to all 3 sides, you get
-10%2B230%3C=t%3C=10%2B230
highlight%28220%3C=t%3C=240%29
