Answer:
7 and 2?
Step-by-step explanation:
i think because f(2) : f(x)= 5+2x = 7
The measure of angle B can NOT be determined as it must give the length of the third side, or one angle in the triangle at least.
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<u>></u>20' and '3.50p+8h<u><</u>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

Answer:
c = 2.99m+ 6.85
Step-by-step explanation:
one time fee of 6.85
2.99 per movie rental
in other words you must pay 6.85
and 2.99 times the number of movies you watch
m = movies watched
c = cost
therefore
c = 2.99m+ 6.85
watching 13 movies at movie mania would mean that m (movies watched) would be 13
put that into the equation:
c = 6.85+ 2.99(13)
c = 6.85+ 38.87
c = 45.72
