Best ResponseYou've already chosen the best response.0I need help with 2 and 3 2.The inequalities: Show the work for finding the inequality that defines each segment. 3.A point: Choose a point within the boundaries of the shape, and show algebraically that the point satisfies all of the inequalities

Best ResponseYou've already chosen the best response.2First find the equations for each of the lines

Best ResponseYou've already chosen the best response.2eg The line joining (4,8) and (9,13) is y = x + 4

Best ResponseYou've already chosen the best response.0how did you get that?

Best ResponseYou've already chosen the best response.2and area under that is y > x + 4

Best ResponseYou've already chosen the best response.0y > x + 4 is 4,8 to 9,3?

Best ResponseYou've already chosen the best response.2first find the slope y2  y1  = (13  8) / (94) = 1 x2  x1 Then plug this and one of the points into the general equation y  y1 = m(x  x1) y  13 = 1(x  9) which simplifies to y = x + 4

Best ResponseYou've already chosen the best response.2now you need to do that for the other 3 lines

Best ResponseYou've already chosen the best response.0So if (4,8) to (9,13) is y = x + 4

BioHazard9064

Best ResponseYou've already chosen the best response.0Then y2  y1  = (4  8) / (9  3) = ? x2  x1

Best ResponseYou've already chosen the best response.2no this line has negative slope and is at right angles to the one joining (4,8) and (9,13) so its slope is 1 yy1 = m(x  x1) y  8 = 1(x  4) y = x + 4 + 8 y = x + 12

Best ResponseYou've already chosen the best response.0is that for 9,3 or 9,13?

welshfella

Best ResponseYou've already chosen the best response.2that is the equation for the line joining (4,8) and )9,3)

Best ResponseYou've already chosen the best response.0so for 9,13 to 14,8 is the same then?

Best ResponseYou've already chosen the best response.2sorry  i'm ok in English  not brilliant

BioHazard9064

Best ResponseYou've already chosen the best response.0so from 9,13 to 14,8 it would be y = x + ?

welshfella
 one year ago
Best ResponseYou've already chosen the best response.2yes but you'll need to plug in one of the points  use (9,13)

BioHazard9064

Best ResponseYou've already chosen the best response.0ok so it would look like

Best ResponseYou've already chosen the best response.2y  y1 = 1(x  x1) y1 = 13 x1 = 9

welshfella

Best ResponseYou've already chosen the best response.2you have to always that general form yy1 = m(x  x1)

BioHazard9064
 one year ago
Best ResponseYou've already chosen the best response.0ok so then it would look like this? y = x + 9

welshfella

Best ResponseYou've already chosen the best response.2y  13 = 1(x  9) now isolate y and simplify the RHS

welshfella
 one year ago
Best ResponseYou've already chosen the best response.2y  13 = x + 9 now add 13 to both sides

BioHazard9064

Best ResponseYou've already chosen the best response.013 and 13 so that would be y=  x + 22?

BioHazard9064
 one year ago
Best ResponseYou've already chosen the best response.0ok so that would be 9,13 to 14,8

welshfella

Best ResponseYou've already chosen the best response.2we've just done that one

welshfella

Best ResponseYou've already chosen the best response.2lets see what we've got so far y = x+ 4 y = x _ 12 y = x + 22 oh we haven't done (9,30 to (14,8)

Best ResponseYou've already chosen the best response.0I dont know how to start it

Best ResponseYou've already chosen the best response.2I 'll have to look the stuff over again I'm not sure if i'm right. Give me a minute

welshfella

Best ResponseYou've already chosen the best response.2yea the 3 we've done are ok thats y = x + 12 though for the line from (9,3) to (14,8) slope = 1 take the point (9 ,3) y  3 = x  9 y = x  6

welshfella
 one year ago
Best ResponseYou've already chosen the best response.2so theres the equation for 4 lines y = x+ 4 y = x + 12 y = x  6 y = x + 22

welshfella
 one year ago
Best ResponseYou've already chosen the best response.2yw so the inequalities are y <= x + 4 y >= x + 12 y >= x  6 y <= x + 22 that defines the shaded diamond
