Try to put the values in the given inequality. For example : \(y\ge 4x5\) \(\text{Put the ordered pair of (x,y) , let it be that of 1st option}\) In 1st option given, x=3 and y = 4 \(4\ge 4(3)5\) \(4\ge 125\) \(4\ge 7\) what do you think is it true that 4 is greater or equal to 7

You have 4 stars : \(\star \star \star \star\) and your friend has 7 stars: \(\star \star \star \star \star \star \star \) Who has more?

i guess its D, substitute the values and find them

Right. so finally 4 is greater or less then 7 ?

mathsloverBest ResponseYou've already chosen the best response.2
Good. so can you now substitute values of other options as I did and tell me which is the answer?

I'm not sure how to do so, I mean I'm not very good at this type of math.. Is it D..?

mathsloverBest ResponseYou've already chosen the best response.2
Yes , it is but that is what told by @miteshchvm already, OK, first of all just tell me what will be : \(y\ge 4x5\) put y = 1 and x = 2 What do you get?

Okay one question first. Um.. like I said, I'm not very good at this type of math and I did guess because I don't know how to do it. But the question is: when I replace x would that be 42 or 4*2 which would be 8..? And @sauravshakya I am too haha. Seems like an official teacher. @mathslover please have patience. (:

Thanks @sauravshakya and no, @zigzagoon2000 I am not an official teacher :). OK, now coming to the point. @zigzagoon2000 always remember that whenever you are given : \(4x , 5y , 6a\) where 4,5,6 are constants and x,y,a are variables then it is : \(4x = 4\times x\) \(5y = 5\times y\) \(6a=6\times a\) Hence when you put x = 2 in 4x then you get : \(4x=4(2) = 4\times 2 = 8\) Refer writing that as 4(2) rather than 42 ... It avoids confusion.

I see, thank you very much for the explanation.. One of the many that are needed in my case. So the answer to your original question would be: 1≥8  5, which would be 1≥3.

Very good. You are correct . Similarly find for other values given in options and then you will arrive to a correct answer. Thanks!

What does this symbol even mean "≥"? I know what > means but I don't know what it means with the line underneath.

mathsloverBest ResponseYou've already chosen the best response.2
\(\ge \implies \text{Greater than or equal to}\) the line underneath the > represents > equal to sign
