Help, will medal =))

zarkam21 (zarkam21):

OpenStudy (gorv):

put each point in both equation

OpenStudy (gorv):

consider (1,0) that is x=1 and y=0

OpenStudy (gorv):

y<=5x-4 0<=5*1-4 0<=5-4 0<=1 which is ture so this point is solution of this in equality

OpenStudy (gorv):

sorry true

OpenStudy (gorv):

y>=-3x+4 0>=-3*1+4 0>=1 which is false so it is not the solution of this so this point do not satisfy both so it is not the ans

OpenStudy (gorv):

try plugging in each point and the point which will be true for both inequality that will be our solution

OpenStudy (gorv):

(2,6) try this and tell .....is it the solution ?? @zarkam21

zarkam21 (zarkam21):

Yes

OpenStudy (gorv):

good ...now go for next one (2,-2)

zarkam21 (zarkam21):

So B,C,D, and E

OpenStudy (gorv):

check C

zarkam21 (zarkam21):

So B,D and E

OpenStudy (gorv):

not D :)

zarkam21 (zarkam21):
