Answer:
x = 2
Step-by-step explanation:
x/(x+1) = (x+6) / (x+10)
the 10 comes from 9+1
Then cross multiply and solve for x
the terms cancel out just leaving behind a nice linear function.
1- increase (0,4) (0,oo) decrease= (4,0)
2. Max- 4 min-0
3. (-2,0) (1,0)
4. Domain [-2,oo) range [0,oo)
The expression would be s/10.
i.e. If you have 20 sponges and 10 sponges are in each package, the number of packages would be 2 because of 20/10.
Answer:
u= 230
Step-by-step explanation:
1 dozen of calculators = 12 calculators
Selling calculators at $20 for every 3 calculators is the same as selling calculators at $80 for every 12 calculators, or 1 dozen.
b=number of dozen of calculators bought, or 6
s=number of dozen of calculators sold, or 6
p=amount of profit
65(b)-80(s)=|p|
65(6)-80(6)=|p|
390-480=|p|
-90=|p|
90=p
The profit on six dozen calculators is $90.
