For what values of x is the absolute value of x less than or equal to 1.5? (Hint: Substitute numbers into the inequality | x | ≤ 1.5 and see which numbers make the inequality true.) Choose three other positive numbers and answer the question using those numbers. Make a conjecture about when the absolute value of x is less than or equal to a given positive number a.

Respuesta :


|x|<1.5
if x=0
0<1.5 is true
if x=1.5
1.5<1.5
true

if x=-1.5
|-1.5|<1.5
anything greater than 1.5 or less than -1.5 doesn't work


the way to solve is
assume that the inside is negative so if you had
|x|=a then to solve
x=a
x=-a
