Final answer:
To find where f(x)=0, also known as the root or solution of the function, you need to know the specific function. With the specifics of the function, you could then solve for x using methods like factoring, completing the square, or the quadratic formula.
Explanation:
In mathematics, when we say f(x) = 0, we are seeking for the values of x that would make the function f(x) equal to zero. This is traditionally referred to as finding the root, zero or solution of the function. However, without a specific function, such as f(x) = x^2 - 4 for example, we can't specify which values x may take. If we knew more about the particulars of the function, we could use a variety of methods such as factoring, completing the square, or using the quadratic formula to solve for x.

In this case, 40 hectograms is equal to 4000 grams.
To convert hectograms to grams, we need to know that 1 hectogram (hg) is equal to 100 grams (g).
Now, let's calculate the number of grams in 40 hectograms:
1 hectogram = 100 grams
Therefore, 40 hectograms will be:
40 hectograms = 40 * 100 grams
40 hectograms = 4000 grams
So, there are 4000 grams in 40 hectograms.
In summary, to convert hectograms to grams, we use the conversion factor of 1 hectogram = 100 grams. By multiplying the number of hectograms by 100, we get the equivalent weight in grams. In this case, 40 hectograms is equal to 4000 grams. This conversion is based on the metric system, where prefixes like hecto- and kilo- represent multiples of 100 and 1000, respectively, making it easy to convert between different units of weight.

K: Kilos
H: Hecto
D: Deka
B: Base (liters or grams etc.)
D: Deci
C: Centi
M: Milli
Now, since you are going from hectograms (hecto) to grams (base) you will move the decimal to the right 2 times (since base is 2 bellow hecto) So that means: There are 4,000 grams in 40 hectograms.

Note: A dime is worth 10 cents and a quarter is worth 25 cents. Therefore, their coefficients would be 0.1 and 0.25 (you must divide them by 100, since 1 dollar = 100 cents).
Now you can set up a system of equations and solve by substitution.
x + y = 18
0.1x + 0.25y = 2.85
In order to substitute, you have to solve for one of the variables in terms of the other. This will be easiest to do with the first equation.
x + y = 18
y = 18 - x
Now, substitute in that value of y into the second equation.
0.1x + 0.25(18 - x) = 2.85
Now, you can solve for x.
0.1x + 4.5 - 0.25x = 2.85
- 0.15x = -1.65
x = 11
You have 11 dimes.
Now you can substitute that value into your original first equation.
(11) + y = 18
y = 7
You have 7 quarters.
Answer: 11 dimes and 7 quarters
