Svetlana's hair is 4 4 centimeters ( cm cm) long. her hair grows 1 . 5 cm 1.5cm per month. svetlana wants her hair to be less than 1 6 cm 16cm long. write an inequality to determine the number of months, m m, svetlana can allow her hair to grow so that it is less than 1 6 cm 16cm long.

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?
