Answer:
Step-by-step explanation:
In general, graphs that go from lower left to upper right have a positive slope (think of it as going up the stairs...positive), and graphs that go from upper left to lower right have a negative slope (think of it as going down the stairs...negative). I don't see graphs here but use this general idea and you'll be fine. Of course, this applies to graphs of lines of the form y = mx + b.
About 40%
186---100%
75-----x%
75*100 divide by 186
Answer:
0.125
Step-by-step explanation:
This is a standard calculus question. If you search out L'Hopital's Rule you will find that there are only Calculus examples present. If you use calculus, the answer comes to 1/8. The only way I can think of doing this without the use of Calculus is to let x = something very small -- say x = 0.0001 That approaches 0, but it is not quite = to 0.
So let's try it.
16 + 0.00001 = 16.00001
sqrt(16.0001) = 4.00000125
Now subtract 4
4.00000125 - 4
0.00000125
Now divide by 0.00001
0.12499998
which is close to 0.125.
If someone else can give you an answer that is "purer" than this one, take it.
(400x) + (500x) + 600 = 900x +600
You'll need to create two equations and have a 'system of equations' then use direct substitution to turn the equation into one. Whichever equation is easiest to solve for x or y. Solve that one for x or y and plug the result in for the variable in the other equation. Then you will have an equation with only 1 unknown.
