Lincoln Middle School has a total of $200 to spend on notebooks and tablets for the school board meeting. Notebooks cost seven dollars each, and tablets cost five dollars each. If x represents the number of notebooks and y represents the number of tablets, which graph correctly shows the solution to the problem?

yes
@mathmale
does anyone know any answers
@Hero
i think so
I think its a but, im terrible in math
can u re post your question

and the urls above are the graphs which are the answer choices.

i have more questions also.
heres another one maybe you could help me with.
Which correctly describes how the graph of the inequality -4y - x ≥ 7 is shaded? Above the solid line Below the solid line Above the dashed line Below the dashed line
and this other one Which inequality matches the graph? X, Y graph. X range is negative 10 to 10, and Y range is negative 10 to 10. Dashed line on graph has positive slope and runs through negative 10, negative 9 and negative 1, negative 3 and 8, 3. Above line is shaded. -2x + 3y > 7 2x - 3y < 7 -3x + 2y ≥ 7 3x - 2y ≤ 7
The links for the answer choices don't work, could you try doing a screenshot or something? :)
the graph to the last one i posted is ...... http://learn.flvs.net/webdav/assessment_images/educator_algebra1_v17/05_05_quiz/05_05_graph_8.gif
I'm getting this message http://prntscr.com/3a1wwl which usually happens when I'm not allowed on your online school :P
me too
and please only post one question at a time...
How about lets try the Lincoln Middle School one first? :) (money amount)(object) + (money amount)(object) = (total amount of money for all objects) so you can get equation 7x + 5y = 200
hey sorry eating dinner
so you need me to post the pics?
Those are the answer choices for the Lincoln question
alright :) so they want to spend less than or equal to 200 right?
right
so equal to would have a solid line and less than means that it would be shaded under right?
i guess i dont really no, i would asume so though because less would be down and greater would mean above.
correct :)
dont they all have a solid line though.
well, you would want to choose the option that does have the solid line then, right?
im asking i thought they all have a solid line.
well I'm pretty sure the last options doesn't if you look closely :)
oooh, isee some have dotted lines and some have solid lines, i was so confused lol. but the correct answer is one with a solid line thats also less so its on the bottom that would be the first option a
Correct! :) Great Job ^_^
can you help me with two more?
I can try...
Which correctly describes how the graph of the inequality -4y - x ≥ 7 is shaded? Above the solid line Below the solid line Above the dashed line Below the dashed line
well first solve for y like you would if it were an equation :)
im not really good at this. but ill try.
i have no clue.
add 4y to both sides subtract both sides by 7 divide both sides by 4
i dont understand how you would add 4y to oth sides.
would it be x >/ 7 +4 y ???
negative x but yes :) then subtract 7 from both sides and divide both sides by 4 :)
-7x>/+4y?
-7 - x >/ 4y :)
then divide both sides by 4
1.75-x>/y ?
-1.75***
yes :)
im still confused what the answer is.
well, the or equal to line would mean that it's solid and if it is < y then it's above and if its > y then it's below :)
so its below.
Below the dashed line.............. is this the answer.
well, "≥" has an "or equal to" line right? and "the or equal to line would mean that it's solid"
so below the solid line. is correct
yes :)
i have one more (:
okay :)
Which inequality matches the graph? -2x + 3y > 7 2x - 3y < 7 -3x + 2y ≥ 7 3x - 2y ≤ 7
since its a dashed line that illuminates c and d
you're right :) then we can use the same idea as before and solve for y to see if it's shaded above or below
and its above , so itd have to be y > so i think the answer is a
because in answer choice a its -2x + 3y > 7 and there is y >
Correct! :) just be careful if it had been a -y then it wouldn't be true :P but you've got it right ^_^ A is correct
i got it wrong, but the other two you helped me with were right.
awww, sorry about that... :/ well, I'm glad I could help :)
thank you
