Question

If x is less than 2 then which of following statements are always true?
(a) x is negative
(b) x is positive
(c) x2 is greater than or equal to 2
(d) x2 is lesser than or equal to 2

Answer 1

What do you think is the answer?

Answer 2

not at all idea

Answer 3

Well, give me your best guess! We can work from there!

Answer 4

consider each one in turn
(a) - is x necessarily negative?

Answer 5

d?

Answer 6

1 is less than 2

Answer 7

ok, x can be anything less than 2... so it can be 1, 0, -1, -2, -3 etc.

Answer 8

@welshfella ,bt we cant say x will be negative as x can be =1 as well

Answer 9

So out of all the answers I would have to agree that D is the answer unless there is more to the question

Answer 10

Because x could be a negative and it could be a positive so that rules out a and b.

Answer 11

yes definitely not a or b

Answer 12

yup @vanessaperezxo

Answer 13

The question is telling you that x is less that 2 (x<2) so there is no possible way that the answer is c... because x can NOT be greater than 2

Answer 14

now as for c
x can be 1 and 1^2 = 1

Answer 15

So, that leaves you with D

Answer 16

but if x = 1.9 x^2 = 3.61

Answer 17

:( ....den what is the ans

Answer 18

none are always true

Answer 19

@welshfella but remember the question is telling you that x is less than 2.. so.. c is saying that x is greater than 2

Answer 20

tbh d only makes sense because it says anything less than 2... but it also says less than or equal to and the problem doesn't tell you it's equal to it

Answer 21

If I could pick 2 I would go with a and b because it could be positive or negative.

Answer 22

no neither of them are always true - that's the key word ALWAYS

Answer 23

are you sure you have the questsion correct @yashiii

Answer 24

yup question is correct @welshfella

Answer 25

And the answers are correct too?

Answer 26

yup dr

Answer 27

ohhh wait! I got it!

Answer 28

if we take the answers as they are written then none of them are always true.

Answer 29

in this answer you can pick more than one! So the answer is A and B.... Because it is asking which one is ALWAYS TRUE.. A and B are always true... always

Answer 30

Because x can be a positive so thats true.. but x can also be a negative, which is also true!

Answer 31
