Question

Help with a few inequalities questions?

Answer 1

Choose the last step in the given solution to the inequality 6x - 2 < 8x + 4.

(inequality has line under)

Answer 2

Choose the missing step in the given solution to the inequality -4x - 10 > 18 - 2x.

Answer 3

For the first one are you just trying to figure out what to do after?

Answer 4

haha maybe i should have read the top..

Answer 5

@Emah yeah, after we completed those 3 steps we're supposed to say what the last one is

Answer 6

ok... then you would just divide by -2. giving you x on one side and 3 on the other..

Answer 7

@Emah so it would be x < 3

(line under inequality)

Answer 8

6x-2<8x+4
-2x-2<4
-2x<6

Last step you divide by -2. Whenever you divide by a negative the sign flips.
So..
-2/-2x<6/-2
x>-3

Hope this helped. :o)

Answer 9

Almost, but whenever you divide by a negative( or multiply) you have to flip the sign.

Answer 10

i see, thanks for the help. can you help me with the second question?

Answer 11

yup.. you would then combine the like terms..

Answer 12

how do we do that? i've forgotten

Answer 13

so
-4x-10>18-2x
+2x +2x
-2x-10>18
+10 +10
-2x>28

Answer 14

then we divide by 2?

Answer 15

negative 2 yes.

Answer 16

Have you got it?

Answer 17

b?

Answer 18

-2x - 10 < 18
-2x - 10 > 18
-10 > 18 - 2x
10 < 18 + 2x

Answer 19
