Question

If u is an algebraic expression and c is a real number such that c>0, then the equation |u|>c is equivalent to a. u>-c or u>c. b. u<-c or u>c. c. u<-c or u

Answer 1

Answer: u<-c or u>c (choice B)

Step-by-step explanation

Consider the example |x| > 5.

On a number line this will mean either x > 5 or x < -5. We're looking for values of x such that they are more than 5 units away from 0.

A value like x = -7 fits the description (since it's 7 units away from 0). While something like x = 1 isn't a solution.
