Slope intercept form:
(y2-y1)/(x2-x1)
(-1-(-1)/(6-5)=
0/1=
0
Slope is zero
So, since y is always -1 and the slope is zero, the equation will e
y= -1
Answer:
![\displaystyle 11,3](https://tex.z-dn.net/?f=%5Cdisplaystyle%2011%2C3)
Step-by-step explanation:
Use the Law of Cosines to find the length of the third edge:
<em>Solving for Angles</em>
![\displaystyle \frac{a^2 + b^2 - c^2}{2ab} = cos\angle{C} \\ \frac{a^2 - b^2 + c^2}{2ac} = cos\angle{B} \\ \frac{-a^2 + b^2 + c^2}{2bc} = cos\angle{A}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7Ba%5E2%20%2B%20b%5E2%20-%20c%5E2%7D%7B2ab%7D%20%3D%20cos%5Cangle%7BC%7D%20%5C%5C%20%5Cfrac%7Ba%5E2%20-%20b%5E2%20%2B%20c%5E2%7D%7B2ac%7D%20%3D%20cos%5Cangle%7BB%7D%20%5C%5C%20%5Cfrac%7B-a%5E2%20%2B%20b%5E2%20%2B%20c%5E2%7D%7B2bc%7D%20%3D%20cos%5Cangle%7BA%7D)

therefore for every 1 sixth-grader there is 2 seventh graders
Answer:
your answer would be $1.45
Step-by-step explanation:
if you first subtract the price of the fries from the total amount that would be $7.25. Now you have the price of all 5 sliders, so to find the amount of a single slider, you would need to divide the total amount of all 5 sliders by 5. Your equation would be 7.25÷5=1.45
I hope this helps! Have a good day!
