Question

The coordinate plane below represents a city. Points A through F are schools in the city.https://www.connexus.com/content/media/948094-7112013-24001-PM-1247936879.jpg Part A: Using the graph above, create a system of inequalities that only contain points C and F 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 C and F are solutions to the system of inequalities created in Part A. (3 points) Part C: Natalie can only attend a school in her designated zone. Natalie's zone i

Answer 1

you have to log in to see the graph....so I can't see it

Answer 2

ok here it is

Answer 3

let me fix the question right quick though i made an error here

Answer 4

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's zone is defined by y<-x-1. Explain how you can identify the schools that william is allowed to attend.

Answer 5

@Anyone that can help. This and one more is all i need

Answer 6

y < 4x - 5 ...
graphed :
y intercept is : (0,-5)
x intercept is : (5/4,0)
it will be a dashed line, and since it is less then, it will be shaded below the line
start at (0,-5) and since slope is 4, go up 4 and to the right 1, and up 4 and to the right 1, and you should cross the x axis at (5/4,0)

now to check...sub in your points into the inequality to see if they are true

check...
(3,1)...x = 3 and y = 1
now sub
y < 4x - 5
1 < 4(3) - 5
1 < 12 - 5
1 < 7 (correct)

y > -x + 1
graphed :
y intercept is : (0,1)
x intercept is : (1,0)
it will be a dashed line, and since it is greater then, it will be shaded above the line
start at (0,1) and since the slope is -1, go down 1 and to the right 1, and down 1 and to the right 1, and you should cross the x axis at (1,0)

you can verify that these points satisfy the inequality by subbing them into the inequality to see if they are true

check..
(2,-3)..x = 2 and y = -3
now we sub
y > -x + 1
-3 > -2 + 1
-3 > -1 (correct)
=========================
y < -x - 1
slope is -1
y intercept is : (0,-1)
x intercept is : (-1,0)
shading occurs below the line

so after you plot your intercepts, and shade below the line, William's zone contains : B and C
