Question

Solve for x.
-ax + 2b > 8


x < the quantity negative 2 times b plus 8 all over negative a
x > the quantity negative 2 times b plus 8 all over negative a
x < the quantity 2 times b minus 8 all over negative a
x > the quantity negative 2 times b minus 8 all over a

Answer 1

those are the choices

Answer 2

one minute

Answer 3

what you do is try to get x by itself
\[-ax+2b>8\]

\[-2b -ax -2b > 8 - 2b\] subtract 2b from both sides

\[\frac{ -ax }{ -a}< \frac{ -2b+8 }{ -a }\] divide both sides by -a, if you divide by a negative number, you switch the sign from > to <

which results in \[x<\frac{ -2b+8 }{ -a}\] being your answer

Answer 4

tell me if you misunderstand or dont see how i did something

Answer 5

yep nsellers23 is correct

Answer 6

thats what I got too

Answer 7

Not totally understand somewhat thanks

Answer 8

Answer 11

ill try and explain it in more depth if i can

Answer 12

can u help with this

Answer 13

well someone please correct me if i am wrong but i believe all you have to do is get the r by itself by doing:
start: \[C=2\pi r\]
step 1: divide by sides by \[2\pi\] to get r by itself.
result: \[r=\frac{ C }{ 2\pi }\]

If i'm wrong someone, please correct me but to my knowledge is this how its done.

Answer 14

yes that is the correct thing to do. its been confirmed.

Answer 15

Last ? ok

sure lets try that for this one

Answer 21

I think it is A or D

Answer 22

I leaning towards A though

Answer 23

@nsellers23

Answer 24

im actually getting b because you start with \[\frac{ 9 }{ 2 }(35+b)=A\] and you multiply both sides by 2 from the \[\frac{ 9 }{ 2 }\] then you end up with \[9(35+b)=2A\] now divide by sides by 9 getting you \[35+b=\frac{ 2A }{ 9 }\] now subtract 35 from both sides because its positive, making this final answer \[b=\frac{ 2A }{ 9 }-35\]

Answer 25

make sense?

Answer 26

Ok now i see how u do it thanksssss :) i'm going to make another ? tag u so i can give u another medal is that alright
