Best ResponseYou've already chosen the best response.1\[d4>0\] Move the "4" to the LHS and change the sign to +4" \[d>4\] There's your answer.

Best ResponseYou've already chosen the best response.1Look at what I did in my first comment. Read the statement(s).

Best ResponseYou've already chosen the best response.1It's the same as d4=0 but then you have an inequality sign instead of the equal sign. Sometimes inequality signs can get tricky. But in this case, it's simply imagining that the inequality sign is an equal sign.

Best ResponseYou've already chosen the best response.1d4=0. What does d equal?

Best ResponseYou've already chosen the best response.1To solve that step by step, wouldn't you move the 4 to the other side? (even though you can mentally solve that in your head)

Best ResponseYou've already chosen the best response.1You just have to solve all of them and figure out which one matches. d + 4 < 0 4 4 d<4 d + 2 > 2 2 2 d>0 d  4 > 0 +4 +4 d>4 d + 2 < 2 2 2 d<0 So d>4 would be d4>0 Hope that makes sense :o)

Best ResponseYou've already chosen the best response.1If you were given these choices, you wouldn't need to solve them all one by one. If you were given these choices, all you have to do is look at the inequality signs. If the inequality sign does not match the inequality sign in your question, then that choice is eliminated. It will be between the second choice or the third choice. Now look at the number. The second choice has the number "2", while the third option has the number "4". Which number matches the number in your question? Obviously the number 4. That means the third option is the correct choice.

Best ResponseYou've already chosen the best response.1That can be another way of solving this. NOTE: This only works with adding and subtracting. If it comes to dividing and multiplying with the inclusion of negative numbers, then it becomes a whole different ball game.
