Can someone help me with this question? It's a little tricky.

MsBrains (ms-brains):

A= -7 B = -19 C= -33 D= -43 I don't know which to choose. None make sense..

OpenStudy (igreen):

Show me your steps.

MsBrains (ms-brains):

This one is for A, Do you want me show them for the other three as well?

OpenStudy (igreen):

Solve the inequality. \(\sf -2x - 13 \le 7\) Add 13 to both sides, can you do that?

MsBrains (ms-brains):

Yes, I can. I simplified it to x > -10

OpenStudy (igreen):

Correct, but remember the 'or equal to'. \(\sf x \ge -10\) Now look at the answers and see which one's are greater than or equal to -10.

MsBrains (ms-brains):

Okay, so just -7 will be the one that is greater than? Because these are negative numbers

hartnn (hartnn):

aren't the options given to be 3,-3, -10,-15 ? and except -15, all others are greater than or = -10

hartnn (hartnn):

if A= -7 B = -19 C= -33 D= -43 are the choices, then yes, -7 is correct.

MsBrains (ms-brains):

Wait, actually you are right @hartnn It should A, B, and C, that are correct. I need to pick more than 1 correct answer... At least that's what I think it means..

hartnn (hartnn):

yes, it does. pick all the answers that are correct.
