we are given system of inequality as


now, we can check solution
At (0,0):
we can plug x=0 and y=0
and check inequality


so, this is FALSE
now, we can check second inequality


So, this is TRUE
so, option-B

Answer:
One year ago, he had height of 150 cm.
Step-by-step explanation:
We have to model this situation.
The first step is having everything as the same unit. I am going to work in meters initially.
Each m is 100 cm. So 10cm = 10/100 = 0.1m.
I am also going to say that his height one year ago was x.
His height is now 1.6m, which is 10cm = 0.1m above his height last year, which was x. So



His height last year was 1.5m.
In centimeters, that is 1.5*100 = 150 cm.
