Best ResponseYou've already chosen the best response.1Yes, but we would never express the answer that way. You want an inequality involving only x, not x, hence .... x ....

Best ResponseYou've already chosen the best response.0Oh, okay so it's x ≤ 14?

Best ResponseYou've already chosen the best response.1No. Careful. a < b <=> a > b

Best ResponseYou've already chosen the best response.1if \[ x \leq 14 \] that can NOT mean that \( x \leq 14 \). For example, when x = 15, \( x = 15 \leq 14 \) is true, but \( x =15 \leq 14 \) is definitely false.

Best ResponseYou've already chosen the best response.0Okay, so is all of it wrong?

Best ResponseYou've already chosen the best response.1No. What I am saying is you want to have an inequality involving only x, not x. The inequality \[ x \leq 14 \] is equivalent to \[ x \geq 14 \]

Best ResponseYou've already chosen the best response.0Oh, okay I get it now. So I should shade it to the left, correct?

Best ResponseYou've already chosen the best response.1No. x is greater or equal to 14, so it is that part of the number line to the right of 14, including 14 itself.

Best ResponseYou've already chosen the best response.0Closed circle shade to the right?

Best ResponseYou've already chosen the best response.1Yes, as the shaded circle indicates you include that value, in this case 14.

Best ResponseYou've already chosen the best response.1btw, whenever you do these things you should double check with the original expression. Put in x = 14 and x = 15 and make sure you get the results you expect.
