please try to ask seperate questions instead of asking a whole bunch of questions (my opinion)
answers since too much work to show completely
17. x=5, y=1 so the annswer is (5,1)
18. quarters are worth 0.25 and nickes are woth 0.05, represent quarters as q and nickels as n so total cois=n+q and total value=0.25q+0.05n .total= 30 so the equations would be
n+q=200
0.05n+0.25=30
answer is n=100
19. answer x=-1 y=4 so answer is (-1,4)
20. so 12=4r+1b and 8=1b+2r
answer red=2lb blue=4lb
21. the only one in the shaed are is (1,-4)
(1,-4) is the naswer
22. it satisfies only one and is NOT part of the solutin set
23. the answer with 'h>20' and '3.50p+8h<200 (the third one) is correct
24. so jusr remember it is in (x,y) form so just look for the coorrect answer
answer is the fourth one (0,0), (0,1) , (6,3), (6,13)
25. not sure but min is 2
26. y=2
second one
27. y<-5/4x+3 first one
