Question

will fan, medal and testimonial...i really dont get this.

Answer 1

The coordinate plane below represents a city. Points A through F are schools in the city.

Answer 2

Part A: Using the graph above, create a system of inequalities that only contain points D 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 D and E are solutions to the system of inequalities created in Part A. (3 points)

Part C: Timothy can only attend a school in his designated zone. Timothy's zone is defined by y < 3x - 3. Explain how you can identify the schools that Timothy is allowed to attend. (2 points)

Answer 3

For Part A I put y<-2x+5..?

Answer 4

@aum

Answer 5

You need to make a system of inequalities.

Answer 6

That means more than one.

Answer 7

Make one inequality to the left of D, and one to the right of E.

Answer 8

i figured lol :(

Answer 9

Are you having troubles finding a line that'll fit?

Answer 10

i'm having trouble with the entire thing, really..

Answer 11

i've been working on the same test for close to 3 hours and this is the last question lol

Answer 12

A practice test, I'm assuming.

Answer 13

yeah, actually :p. i'd be screwed if it weren't

Answer 14

can you shed some light on this?

Answer 15

Well, for Part A, I'd start out by finding the equation of the line that has the points C and B. Then, find the equation of the line that has the points A and B.

Answer 16

....can you do that for me

Answer 17

Not much point when you'll have to do this eventually, right? Just find the slope (rise over run), then use the equation y - y1 = m(x-x1)

Answer 18

i'll...never have to do this

Answer 19

For example, for the line with points C (2,1) and B (-4, -2), the slope would be 3/6 or 2. The equation would be y - 1 = 2(x-2)

Answer 20

You would then rearrange that equation to isolate for y, then change it into an appropriate inequality.

Answer 21

i'll give it a shot i guess, thanks :p

Answer 22

@aum pls
