F(-x) = 2/-x/ + 3(-x) = 2/x/ - 3x;
300 divided by 15 is 20 so 20 times 15 is 300
Using the 2x+2y=P formula, it equals 34
Answer:
450×6.75 = 2 956.5
So the serviceman will get 2 956.5 after 6.75 hours of doing the job
Answer:
1.59C + 2.25A = 786.75
C + A = 33 (even if all were the higher paying adults, that would only be 33x2.25=74.25 far less than <<786.75)
1.59C + 1.59A = 33(1.59) = 52.47 subtract to eliminate C
(2.25-1.59)A = 786.75 -52.47 = 734.28
.66A = 734.28
A = 73428/66 = 1112.55 = about 1113 adults
C = 33-1113 = -1080 children
which makes no sense. over a thousand "negative" children? the public pool gave refunds to over a thousand prepaid children who didn't show up? but a public swimming pool, no matter how large, probably wouldn't accomodate 1113 adults.
