Answer: 2
Step-by-step explanation: add 2 to 7 you get 9
Answer:
Eric,Tony,Jeff,Gary
Step-by-step explanation:
Given the payments made by each individual below:
- Tony paid 35% of the bill.
- Eric paid 3/8 of the bill.
- Jeff paid 0.175 of the bill
- Gary paid 1/10 of the bill.
The most convenient way to order their payments is to convert each to percentage.
Eric paid 3/8 of the bill.
- In Percentage:
![\frac{3}{8}X100=37.5\%](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B8%7DX100%3D37.5%5C%25)
Jeff paid 0.175 of the bill
- In percentage, 0.175 X100 =17.5%
Gary paid 1/10 of the bill.
In Percentage: ![\frac{1}{10}X100=10\%](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7DX100%3D10%5C%25)
Therefore, the order from most to least is:
Eric(37.5%), Tony(35%),Jeff(17.5%),Gary(10%)
Domain is the sex of x values that are feasible. this is all of the positive integer values + 0, in case you only consider that can produce whole units.
range is the set of possible results for c(x), possible costs.
you can derive this from the fact that c(x) is a parabole and you can draw it, for which you can find the vertex of the parabola, the roots, the y intercept, the shape. also limit the costs to be positive.
you can substitute some values for x to help you, for example.
x y
0 200
1 200 - 7 + 0.345 = 193.345
2 200 - 14 + .345(4) = 187.38
3 200 - 21 + .345(9) = 182.105
the function does not have real roots, then the costs never decrease to 0.
the function starts at c(x) = 200, decreases until the vertex, (x = 10, c = 164.5) and starts to increase
then the range goes to 164.5 to infinity, limited to the solution for x = positive integers.
