since there is an absolute value sign you have to set up 2 equations.
one that says: |4x + 3| ≥ 19 and one that says: |4x + 3| (lessthan / equal to) - 19
do you see how i did that?
I just need to know which one I chose.... I'm on a time crunch
I am so bad at math
im not going to just give you the answer. i will help you understand it tho..
do you want my help?
|dw:1359407665618:dw|okay so you will set them up like this:
you have to set up 2 equations because there is an absolute value sign
after that you solve for x. so start with the positive 19 equation when you solve for x what will you get.
x ≥ 4?
yes, now you got that one.. so just by looking at the answers you know its either a/d now do the second equation. what do you get?
x ≤ -(11/2)?
thats not all the way simplified but you're close , that simplifies down to ?
x ≤ -(5.5/1)?
yes which is also just -5.5 okay and so now you definitely know its either a/d okay the difference between a and d is that the middle word in a is "and" and the middle word in "d" is or.. do you know the difference between those?
okay since you had the absolute value sign i told you before that you had to make two equations. and when you have to make two equations that means both of those answers need to be "included" so it would be "and". do you understand why?
do you understand why now* i should say
Yeah, I think so
okay good ! so your answer is a. good work (:
What about the question with the attachments?
I think it's "a"
just one sec . lemme do it first
yess you are correct!! (: good job (:
Thank you! :D
no problem (:
