Question

Which inequality is true when the value of u is 1? O-- 10 > -1.5 u – 10 > 1.5 O –u – 10 – 1.5 O – 10 >1.5

Answer 1

First, let's solve each one of the inequalities for u

1) -u-10>-1.5

u<-10+1.5

u<-8.5 then this statement is not true for u=1

2) u-10>1.5

u>1.5+10

u>11.5 then this statement is not true for u=1

3) -u-10<1.5

u>-10-1.5

u>-11.5 which is true for u=1

4)-u-10>1.5

u<-11.5 which is not true for u=1

then the correct option will be -u-10<1.5
