Hey there!
Welcome to OpenStudy :)

Answer 3

@TheSmartOne

Answer 4

Thank you @Abhisar

Answer 5

@Abhisar do you mind helping me still. I am still waiting here for help.

Answer 6

Sorry Mathematics is not my forte :(

Answer 7

Oh may you tag someone to help me @Abhisar

Answer 8

@Jhannybean may help you

Answer 9

ax + 4b > 9

Since you're solving for the quantity x, you want to move everything else on to the other side of the \(\gt\) sign

Answer 10

So you'll subtract -4b from both sides of the inequality.

Answer 11

DO that and tell me what you get.

Answer 12

ok hold on

Answer 13

-ax>9 - 4b?

Answer 14

Tell me why you made it negative.

Answer 15

made what negative

Answer 16

Why have you written -ax on the left hand side? you're subtracting -4b from the +4b that is already there. No need to change ax

Answer 17

oh sorry

Answer 18

ax + 4b > 9
- 4b -4b
______________________
ax > 9 - 4b

This is what you got, yes?

Answer 19

no wait there is supposed to be a negative in front of ax so it would be -ax I wrote the equation wrong

Answer 20

So your original equation is

-ax + 4b > 9 ?

Answer 21

yes

Answer 22

sorry for the confusion my bad

Answer 23

No problem :)

Answer 24

So yes, your previous post would be correct.

Answer 25

ok so now we have to continue

Answer 26

-ax > 9-4b \(\checkmark\)

Answer 27

When you divide or multiply both sides of an inequality by a negative value, you always have to flip the sign. This means \(\gt\) will become \(\lt\)

Answer 28

ok

Answer 29

what will I have to do next?

Answer 30

@Jhannybean

Answer 31

So divide both sides of your inequality by -a, this will flip your inequality. What do you get?

Answer 32

i REALLY DO NOT KNOW i AM CONFUSED

Answer 33

It's ok, it's ok. calm down :)

Answer 34

oh sorry did not mean to use caps I am trying to type without having my eyes on the keyboard

Answer 35

\[\frac{-ax}{-a} \gt \frac{9-4b}{-a}\]Like I mentioned, When dividing by or multiplying by a negative number, in this case -a, the sign will FLIP. so what do you end up with?

Answer 36

I do not know

Answer 37

We can eliminate answer choices A and D.

Answer 38

okay

Answer 39

this is just a guess is the answer a

Answer 40

@Jhannybean

Answer 41

... didn't we just say the answer choice A and D can be eliminated?

Answer 42

eliminated means removed, as in they do not count. As in they are not going to be one of your answer choices,

Answer 43

oh sorry I am a hot mess today

Answer 44

I am going to guess on b then

Answer 45

@JhannyBean

Answer 46

Just letting know now, all your answer choices are incorrect for this problem. None of them match up to your function.

Answer 47

they are let me see

Answer 48

Solve for x.

-ax + 4b > 9

x > the quantity negative 3 times b minus 5 all over negative a
x < the quantity 5 minus 3 times b all over negative a
x < the quantity negative 3 times b plus 5 all over negative a
x > the quantity negative 3 times b plus 5 all over negative a

Answer 49

is that better

Answer 50

\[\frac{-ax}{-a} \gt \frac{9-4b}{-a}\]\[x \lt \frac{9-4b}{-a}\]
Or otherwise written as "x < the quantity of 9 minus 4 times b all over negative a"

Answer 51

So I guess b would work here, if that's all you're left to work with :\

Answer 52

may u help me with two more

Answer 53

Sorry, I'll tag in someone else for now. Open up another question and post your problem! More people can help :D

Answer 54

ok
