Question

ok this one is simple looking to figure out if the answer would be negative or positive Y

6 - 13y ≤ 4 - 12y
6 -13y +12y ≤ 4 - 12y + 12y
6 - y ≤ 4
6 - 6 - y ≤ 4 - 6
-y ≤ -2

Answer 1

i would do this in another way..

Answer 2

instead of adding 12y to both sides, add 13 y to both sides

Answer 3

6 ≤ 4 +y

Answer 4

2 ≤ y
or y is more than or equal to two

Answer 5

Please click on become a fan if I helped, I really want to get to 100!! Thanks =)

Answer 6

sorry meant to the next level lol

Answer 7

well what lost me was line 3 as it should read 6-(-y) shouldnt it ?

Answer 8

okay let me try this step by step

Answer 9

6 - 13y ≤ 4 - 12y
6 -13y +13y ≤ 4 - 12y + 13y
6 ≤ 4 + y
6 - 4 ≤ y
2 ≤ y
y \[\ge\] 2

Answer 10

ok so the entire problem was backwords i thought normal operations was to put the variable to the left with numbers on the right ok thanks i think lol

Answer 11

lol sorry, im pretty bad at -y>-x i am never sure if its y<x or anything.. i just try it backwards lol

Answer 12

raj, you did the problem right. the last step is y >= 2. when you multiply or divide by -1 in an inequality, you have to switch the direction of the inequality.

Answer 13

ok thank you its making a little mo anymore its been a few to many years lol been out of school for to long

Answer 14

if you are ever in doubt of whether you have the correct answer, you can test it by plugging in an x-value and see if the answer you got makes sense. since we got x>2, you could plug in x = 3 to the inequality and see if it is true.

Answer 15

y that is

Answer 16

sorry got booted off one system had to log the other in

Answer 17

thank you for your help

Answer 18

no problem
