Answer:
i think the answer is x + 1 / 5x
I am going to say the cheapest would be 65$ would be the answer. Because if you want it to be shipped too you would add 7.25$ to 65$ to what you are paying for. And taking 10 dollars off (subtracting) you would get 62.25$ But if you would take 65$ from you buying it and used the coupon you would have to pay 55$ The cheapest way is to buy that item (the item costs 65$) and use the 10% off coupon.
Answer:
Step-by-step explanation:
(3 - 5)/(12 - 0)= -2/12 = -1/6 is the slope
![\displaystyle y = Atan(Bx - C) + D](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%20%3D%20Atan%28Bx%20-%20C%29%20%2B%20D)
According to this <em>trigonometric function</em>, −C gives you the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL:
![\displaystyle Phase\:[Horisontal]\:Shift → \frac{-\frac{π}{6}}{1} = -\frac{π}{6} \\ Period → \frac{π}{1} = π](https://tex.z-dn.net/?f=%5Cdisplaystyle%20Phase%5C%3A%5BHorisontal%5D%5C%3AShift%20%E2%86%92%20%5Cfrac%7B-%5Cfrac%7B%CF%80%7D%7B6%7D%7D%7B1%7D%20%3D%20-%5Cfrac%7B%CF%80%7D%7B6%7D%20%5C%5C%20Period%20%E2%86%92%20%5Cfrac%7B%CF%80%7D%7B1%7D%20%3D%20%CF%80)
Therefore we have our answer.

NOTE: Sometimes, your <em>vertical shift</em> might tell you to extend the troughs on each end of your graphs, beyond the <em>midline</em>.

7) Factor 3x² - 12
So, look at those 2 numbers, and see what they both have in common.
They are both divisible by 3! So, basically you divide 3x² and -12 with 3.
3(x² - 4)
It would be factorized like that because if you multiply 3 by x², you would get 3x², and if you multiplied 3 with -4, you would get -4.
