OpenStudy (texaschic101):

-2 >= x/27 --- multiply both sides by 27 -54 >= x if there is an equal sign in the problem, it will be a closed circle....and greater then means shaded to the right. So what do you think now ?

OpenStudy (texaschic101):

oh...wait...it can also be x <= -54...so it is less then (shaded to the left)

OpenStudy (anonymous):

it would be C

OpenStudy (texaschic101):

yes..it is C

OpenStudy (anonymous):

:) i knew it

OpenStudy (anonymous):

help with another?

OpenStudy (texaschic101):

sure :)

OpenStudy (anonymous):

OpenStudy (texaschic101):

13r <= -156 --- divide both sides by 13 r <= -156/13 r <= - 12 so r is less then or equal to -12 closed circle, shaded to the left so what do you think now ?

OpenStudy (anonymous):

automatically crosses out C/D there going >

OpenStudy (anonymous):

A :)

OpenStudy (texaschic101):

crosses out b too.....because of the equal sign....it needs a closed circle

OpenStudy (anonymous):

A :)

OpenStudy (texaschic101):

yep ^^

OpenStudy (anonymous):

another?

OpenStudy (texaschic101):

sure :)

OpenStudy (texaschic101):

66 < 6x --- divide both sides by 6 66/6 < x 11 < x or x > 11

OpenStudy (anonymous):

A?

OpenStudy (anonymous):

A or B

OpenStudy (texaschic101):

B

OpenStudy (anonymous):

i was thing tht because dividing is going down

OpenStudy (texaschic101):

you got anymore ?

OpenStudy (anonymous):

https://gyazo.com/6f3180cad24cd04192bc993b86aa6e58

OpenStudy (anonymous):

yes

OpenStudy (texaschic101):

ok....you got an open circle...means there is no equal sign in the problem....that eliminates D. It is shaded to the left....that means less then...that eliminates C. Your open circle is on 2....so that means x is less then 2.....answer is B. Understand ?

OpenStudy (texaschic101):

These can be easily done by process of elimination

OpenStudy (anonymous):

hmm

OpenStudy (anonymous):

makes sense :)

OpenStudy (anonymous):

3 more? :D

OpenStudy (texaschic101):

ok....lets do this :)

OpenStudy (texaschic101):

ok...she does not want to spend MORE THEN $50. That means she can spend 50 or less. So it would be x <= 50.....you have to include the = sign because she can still spend 50.

OpenStudy (anonymous):

D :)

OpenStudy (texaschic101):

the other 2 ??

OpenStudy (anonymous):

i ment C

OpenStudy (anonymous):

not D

OpenStudy (texaschic101):

no...it is D

OpenStudy (texaschic101):

its less then or equal

OpenStudy (anonymous):

https://gyazo.com/0c16e204638adfc5953be9d1eb0eac0b

OpenStudy (texaschic101):

x + 1/4 >= 5/8 --- subtract 1/4 from both sides x >= 5/8 - 1/4 -- common denominator is 8 x >= 5/8 - 2/8 x >= 3/8 equal sign means closed circle....greater then means shaded to the right. answer is B

OpenStudy (anonymous):

https://gyazo.com/eb36f3d0fdae731e706000b26dc09d7d

OpenStudy (texaschic101):

x > 1 3/4 no equal sign, so an open circle....greater then means shaded to the right...answer is D. do you have any questions on anything that I have done ?

OpenStudy (anonymous):

i got 100% :)

OpenStudy (texaschic101):

Thats what I am talking about :)....way to go.

OpenStudy (texaschic101):

congrads.....gonna go help someone else now. Tag me if you need any more help :)
