Desperately need help with algebra! "A laptop advertisement states that internal parts operate at 55° Celsius plus or minus 15°. Write an absolute value equation to represent the situation. Then solve the equation and write it as a compound inequality. State the meaning of the solution."

Best ResponseYou've already chosen the best response.1well i'm not perfect at math so i might be wrong, but from what i understand absolute value equations can have 2 answers, because 6 could mean +or6.. absolute value means it moves in either direction on the number line

Best ResponseYou've already chosen the best response.2first put the equation for variation, next we can account for 55 ok

Best ResponseYou've already chosen the best response.2call "x" the temperature of internal parts at any given time x = 15 but since, the temperature varies around +55, we need to translate the graph to right side : => x55 = 15

Best ResponseYou've already chosen the best response.2yep ! 55 \(\pm\) 15 is correct, but you need to still solve the absolute equation above and write it as compound inequality ! good luck :)

Best ResponseYou've already chosen the best response.0Alright, thanks! The compound inequality would be 40 ≤ x ≤ 70, yes?
