$34 is a proper 20% tip on a $171.81 dinner. Move the decimal point twice to the left, then multiply that twice.
Answer:
n >_ 4
Step-by-step explanation:
move 9 to the other side
n >_ 13 - 9
n >_ 4
A) x + y = 17
B) x * y = -168
y = -168/x then inputting this into A)
x + -168/x = 17
x^2 -168 -17x = 0
x = 24 and x = -7
Answer:
The distance formula is 
The midpoint formula is 
Step-by-step explanation:
apply the pythagorean theorem on a coordinate grid
Usually one will differentiate the function to find the minimum/maximum point, but in this case differentiating yields:

which contains multiple solution if one tries to solve for x when the differentiated form is 0.
I would, though, venture a guess that the minimum value would be (approaching) 5, since the function would be undefined in the vicinity.
If, however, the function is

Then differentiating and equating to 0 yields:

which gives:

or

We reject x=5 as it is when it ix the maximum and thus,

, for
