Question

Which of the equations or inequalities below are true?O A. 4-5 = 1OB B. 4-571O C. 4-5<-2O D. 4-5 2-1

Answer 1

Consider the first option

`4-5=1`

From the left-hand side

`4-5=-1`

But 1 is not equal to - 1

Hence, the equation is not true

Consider the second option

`4-5\\e1`

From the left-hand side

`4-5=-1`

This implies

`-1\\e1`

Hence, the equation is true

Consider the third option

`4-5<-2`

From the left-hand side

`4-5=-1`

Inserting the value into the inequality

`-1<-2`

Since -1 is not less than - 2

Hence, the inequality is not true

Consider the fourth option

`4-5\ge-1`

From the left-hand side

`4-5=-1`

Inserting the value into the inequality

This gives

`-1\ge-1`

Since -1 is equal to -1

Hence the inequality is true

Therefore, the correct options are option B and option D
