Answer:
16.875 spiders
Step-by-step explanation:
Given
Let



So, we have:
--- equal amounts
--- the legs
Required
The number of spider
Since she has an equal amount of B, C and S;
The expression can be written as:



Solve for S


<em>The result of the solution does not represent real life situation because it it is not possible to have a fraction number of spider</em>
Well, keep in mind that the domain of a function is the entire set of possible values of the independent variable. To make it more clear, the domain is the set of all possible x-values, which will make the function work, and with real y-values as the output. So, the range would be the set of all of the second elements of an ordered pair (y-coordinates).
If you made a T chart like the picture you have above, you would have to put x (age of person) and y (books read).
So,
x = age of person
y = books read
8-15= -7
x= -7
I think this is correct..
