Question

Match the inequality with the solution.

TERM:

z + 6(z + 3) < -10

5z + z + 4 > 28

4( z + 1) < 20

-5z + 1 < 13 - 2z




DEFENITION:

z < -4

z > -4

z < 4

z > 4

Answer 1

solve for z, do you know how to solve it was an equal sigh instead of an inequality

Answer 2

I kinda do...I think I do, but I didnt get any of those answers when i did the problems

Answer 3

There is only 1 difference when dealing with inequalities.. When you multiply or divide both sides by a negative number, you flip the less than sign to greather than sign

Answer 4

z + 6(z + 3) < -10
z+6z+18<-10
7z<-10-18
z<-28/7
Z<-4

Answer 5

Why don't you try doing the others

Answer 6

I got Z > -4 because you said to flip the signs

Answer 7

We did not multiply by a negative number, there is no need for flipping

Answer 8

Ohhhh!!!

Answer 9

I get it, thats like the multiplying negatives & positives rule in a way...

Answer 10

i guess. It just kind of makes sense

Answer 11

if you have
-a<-b, and a and b are positive integers so -a and -b are negative for sure..
then you know that for i.e -5 <-4 but 5 is a greater than 4
so when
you multiply bothsides by -1
a>b, we know if -a<-b then on the positive part a should be greater,,,

Answer 12

Alright, thanks :D

Answer 13

okay, just ask me if you need any more clarification on it. I know a good way to visualize it if it needs anymore clarification.
