Question

what are inequalities?

Answer 1

inequalities are just equations that are not equal. for example if you have 5x+3=9 just change this to 5x+3>9 (5x+3 is greater than 9). you solve the inequality the same way as an equation w/the exception of division i believe. in this case you switch the sign (to less than in this case)---

Answer 2

Any expression with \[< > \le or \ge \]

Answer 3

It's not division that flips the sign, it's division by a negative amount

Answer 4

Ok, so how would I do this?
4x < 20

Answer 5

x > 5? is the answer i got but im not completely sure, So what I did was divide each side by 4

Answer 6

How did you know to divide each side by 4? Can you please explain the entire process?

Answer 7

I can try, Ok lets start with taking the given equation 4x > 20
so you take the four, and what we are doing is trying to solve for x.
so we divide each side by the four . so 4 divided by 4 = 1x or just..x and
20 divided by 4 = 5.
________________________
now since theres division you have to flip the sign o: which is how I ended up with x > 5? questions?

Answer 8

Ok i think I've got it now, but can you check this answer for the next one?

Answer 9

-4x < 20 = ????

Answer 10

yeah np, -4x < 20 = (well its basically kinda the same as the last one but I believe this is where you have to flip the greater than/less than sign so it would look like -x > -5
