Question

Solve the exponential inequality. Show all work

33x + 1 ≤ 3x – 9
5x - 4 ≤ 25x – 6
73x + 4≥ 49 2x + 1
92x ≥ 32x + 4
4x + 5 ≥ 21

Answer 1

help

Answer 2

so lets work on the first one together, the 33x + 1 ≤ 3x – 9

Answer 3

what we have to do is collect like terms and we will do this by bringing the 3x to the LHS and the +1 to the RHS, can you do that?

Answer 4

can you show me

Answer 5

33x + 1 ≤ 3x – 9
33x + 1 -3x ≤ - 9 (we subtracted 3x from both sides)
33x -3x ≤ -9 -1 (we subtracted 1 from both sides)
30x ≤ -10
x ≤ (you can figure this out)

Answer 6

hint: when dividing or multiplying negative numbers to both sides, you will have to switch the sign around

Answer 7

thank you

Answer 8

you're welcome

Answer 9

so the other ones the same

Answer 10

like this one

Answer 11

yes, they apply the same concept. pick one of the examples besides the first one which i showed you and show me how you do it

Answer 12

how long you gonna b online

Answer 13

bcuz i need ur help bt im tired

Answer 14

I'll be on here for a while because I'll be asking for help later myself.

Answer 15

for these type of algebra type equations, once you get how to do it, its quite simple. If you understand how to do it try and solve one of the examples yourself and then show me.

Answer 16

okay you gonna b on here tomorrow

Answer 17

if youu r can u give me a time

Answer 18

I'm not sure if I'll be on here tomorrow and even if I am, i'm not sure what specific time anyway.

Answer 23

I'll try to quickly find you a link you can look at to help you with those type of questions

Answer 24

okay thanks

Answer 25

http://www.mathsisfun.com/algebra/inequality-solving.html (website explaining it)
http://www.youtube.com/watch?v=0X-bMeIN53I (this a video on solving linear equations)

Answer 26

so have a look at those tomorrow on when you have time then try do your questions, you shouldn't need any help afterwards but if still do then ask others on here if I'm not online

Answer 27

okay thanks bt is there equations set up like mines

Answer 28

so it can b easier

Answer 29

yes but you do not need any other equations set up like that because it'll be useless if you don't know how to solve those questions that you already have

Answer 30

you have to read/watch the site/video that i told you and re-look at what I did for the first example, then try solve it yourself! you won't learn anything if you don't try and solve or do it yourself.
