medal + fan awaiting please help Which inequality is represented by this graph? A number line shows the numbers zero to ten. There is a closed dot at seven, and an arrow extending from that closed dot toward the right. two x is less than fourteen three x is greater than or equal to twenty-one x divided by seven is greater than or equal to fourteen x divided by one is less than or equal to seven

OpenStudy (swaugh):

where did your response go i was just gonna work it out

563blackghost (563blackghost):

which do you think is right first?

OpenStudy (swaugh):

i would say b or c

563blackghost (563blackghost):

\[A.2x<14\] \[B.3x \le21\] \[C.\frac{ x }{ 7 }\ge14\] \[D.\frac{ x }{ 1 }\le7\] Well what you brought it down to is correct it is either b or c.

OpenStudy (swaugh):

well b is equal to x≤7

OpenStudy (swaugh):

im still working out c

OpenStudy (swaugh):

c = x≥98

563blackghost (563blackghost):

So what answer do you choose?

OpenStudy (swaugh):

is it c

563blackghost (563blackghost):

OMG my mistake the sign for B is the other way....

OpenStudy (swaugh):

thats what im thinking

OpenStudy (swaugh):

but i was following based on what you said

563blackghost (563blackghost):

your simplification was right its just i had the sign the other way which was wrong....but the answer is not quite c. If we inputed 7 for c the simplification would be wrong since 7/7 is equal 1 so 1 is not greater or equal to 14. If we did the same to B we would get 21 in which 21 is equal to 21. And if we inputed a larger number it would be greater than.

563blackghost (563blackghost):

Now you may wonder what about D if i did 7/1 it would equal 7 well yes it would but if we had put for example 21 well 21/1 is 21 and the answer has to be less than or equal to 7 but it is actually greater so D is not right either.

OpenStudy (swaugh):

so the answer is|dw:1446772026989:dw|
