Part A: Using the graph above, create a system of inequalities that only contain points A and E in the overlapping shaded regions. Explain how the lines will be graphed and shaded on the coordinate grid above. (5 points)
Part B: Explain how to verify that the points A and E are solutions to the system of inequalities created in Part A. (3 points)
Part C: William can only attend a school in his designated zone. William's zone is defined by y < x  1. Explain how you can identify the schools that William is allowed to attend. (2 points)

Best ResponseYou've already chosen the best response.1Like where is the system of inequalities or how do i make it???

Best ResponseYou've already chosen the best response.1you can make up anything you want BUT it has to be where the solution for both has to have A and E in it (and only those two points)

Best ResponseYou've already chosen the best response.1what two points lie above point E? ignore the other points A through F

jim_thompson5910

Best ResponseYou've already chosen the best response.1ok I'm going to toss out (3,3) and replace it with (4,3) that way we can draw a line through those two points. This line will be completely above point E

jim_thompson5910

Best ResponseYou've already chosen the best response.1we want to shade below this line, so we could have y < x1

MeowLover17

Best ResponseYou've already chosen the best response.1So now i'm guessing we have to make another line with 2 points under A then shade where they overlap receiving the system of inequalities??

jim_thompson5910

Best ResponseYou've already chosen the best response.1Part A: So to graph the two lines first i must chose two points above points E, in this case i chose points (3,2) and (4,3), now i must draw the line going through these points and i should hit the yaxis at 1. Next i must choose two points under point A, so i choose (2,4) and (3,5) one i've drawn the line through these points i should hit the yaxis at 2. Now i must shade where both A, and E are within these instersecting lines. Which would be on the right side of this graph. Equations= y=x1 & y=x2

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.1ok back yes the two equations are y = x1 and y = x2 the inequalities are y < x1 and y > x2

Best ResponseYou've already chosen the best response.1the inequality includes the shaded region which extends forever downward and to the right (below the line y = x1)

MeowLover17
 one year ago
Best ResponseYou've already chosen the best response.1Okay i see the difference between an inequality and equation, for an inequality you must shade or make dashed depending on if its equal to or not but for an equation you just draw the line.

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.1correct, I forgot about that part

jim_thompson5910

Best ResponseYou've already chosen the best response.1since y < x1 has no line under the < sign, we need a dashed boundary line

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.1but you can easily make it \[\Large y \le x1\]

MeowLover17

Best ResponseYou've already chosen the best response.1Okay so let me show you my answer for part A: Its the same as i showed above just with the inequalities underneath it because i don't know what more to explain.

Best ResponseYou've already chosen the best response.1This is for an online course so i can't draw graphs or anything i just type explanations :/

jim_thompson5910

Best ResponseYou've already chosen the best response.1then do your best to describe the equations/graphs. So mention the points involved and the direction of the shading, and the boundary line type

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.1dw:1433036996621:dw this boundary line goes through (3,2) and (4,3) it is a dashed boundary line (assuming you go with y < x1) the shading is below the boundary line

MeowLover17

Best ResponseYou've already chosen the best response.1Okay let me explain it here then ill transcribe it. Part A: Continuation  After graphing y<x1 i should shade below this line, i can figure this out by testing points above or below the line, i've figured out that points above the line don't work but those underneath do, so this is why i've shaded below y<x1, same for the line y>x2, i shaded above it because when i test points below it does not work, now i can shade infinitley if i wanted too, but i am only shading where both shades meet from y>x2 and y<x1 to receive the system of inequalities...

Best ResponseYou've already chosen the best response.1If i add that on to my first answer does it make it complete?

Best ResponseYou've already chosen the best response.1yes that wraps up part A

MeowLover17

Best ResponseYou've already chosen the best response.1Okay now could you help me answer parts B and C???

jim_thompson5910

Best ResponseYou've already chosen the best response.1Part B: Explain how to verify that the points A and E are solutions to the system of inequalities created in Part A.

jim_thompson5910

Best ResponseYou've already chosen the best response.1I'll show you how to verify point A and I'll let you verify point E

jim_thompson5910

Best ResponseYou've already chosen the best response.1verifying point A point A is (x,y) = (2,3) y < x1 3 < 21 ... plug in (x,y) = (2,3) 3 < 1 ... this is true  y > x  2 3 > 2  2 ... plug in (x,y) = (2,3) 3 > 4 ... this is true  since y < x1 AND y > x  2 are true at the same time for the ordered pair (2,3), this confirms that point A is indeed in the solution set of this system of inequalities

MeowLover17

Best ResponseYou've already chosen the best response.1Oh i see so you just tested point A for both inequalities and it proved true.

MeowLover17

Best ResponseYou've already chosen the best response.1Now i would have to do the same for E

MeowLover17

Best ResponseYou've already chosen the best response.1Okay do i have to show this work or can i just explain it for part B?

jim_thompson5910

Best ResponseYou've already chosen the best response.1showing work is always a good idea, but I guess you could explain it if you want. It will depend on how the teacher wants it

Best ResponseYou've already chosen the best response.1Part C: William can only attend a school in his designated zone. William's zone is defined by y < x  1. Explain how you can identify the schools that William is allowed to attend.

jim_thompson5910

Best ResponseYou've already chosen the best response.1so the goal here is to figure out which points (A through F) satisfy y < x1

jim_thompson5910

Best ResponseYou've already chosen the best response.1and you can use steps similar to what I had done in part B

MeowLover17

Best ResponseYou've already chosen the best response.1Btw pOINTS a THROUGH f ARE SCHOOLS in a city

MeowLover17

Best ResponseYou've already chosen the best response.1So do i just test all points in y>1x to solve for c??

jim_thompson5910
 one year ago
Best ResponseYou've already chosen the best response.1you mean y < x1, right?

MeowLover17
 one year ago
Best ResponseYou've already chosen the best response.1Oh okay so my Answer for Part C would look like Part C: William can only attend schools that satisfy his zone which is y<x1, to figure out which schools would satisfy this i must plug in points A through F into this inequality and see which are true, those that are true are schools that William can attend those that are false or don't make sense are those that he can not attend.

Best ResponseYou've already chosen the best response.1Is this correct???

jim_thompson5910
