If |x + 1| = 6, what are the possible values for x?
A.) -5 and 7
B.) -1 and 1
C.) 5 and -7
D.) 5 and -5
E.) 5 and 7
A.) -5 and 7
B.) -1 and 1
C.) 5 and -7
D.) 5 and -5
E.) 5 and 7
Absolute value is the distance away from zero.
|x + 1| = 6
x + 1 = 6 or x + 1 = -6 {if (x + 1) is 6 away from zero, then (x + 1) could be 6 or -6}
x = 5 or x = -7 {subtracted 1 from each side of each equation}
