How Many Solutions?
How many solutions are there for |x| = 3?
two, 3 and -3
| z - 13 | = 21
What is { -8 , 34 }
Solve the inequality x+5<7
x<2
How many solutions are there for | x | = -2?
No Solutions
| d + 1 | = 7
What is { 6 , -8 }
Solve the inequality 4x>12
x>3
How many solutions are there to |x+1|=2
Two
5 | q + 6 | = 20
What is { -2 , -10 }
Solve the inequality 2x+5<7?
x<1
How many solutions are there for | z + 5 | = 10
Two, 5 , and -15
| p + 1 | + 10 = 5
What is { No Solution }
Solve the inequality -3x>15
x<-5
How many solutions are there for | x+4| = 0
One, -4
| 3n + 18| = 6n
One solution n = 6
Reject n = -2 because it is extraneous.
Solve the inequality -2x+5>9
x<-2
