18 * 3.5 = 63
He wants to fry 63 potatoes
63/6 = 10.5
He will need 10.5 liters of oil to from potatoes for 3.5 hours.
Answer: -rad7, +rad7
Explanation:
- Divide the equation by 6 (x^2-7=0)
- Add 7 (x^2=7)
- Square root x to find solutions (x=rad7)
- Dont forget the radical means that there are two solutions!
I believe you just add all the numbers then divide by how many were there. You would divide by 16.
For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
By definition, if two lines are parallel then their slopes are equal.
We have the following line:

Thus, the slope is:
Then 
So, the line is of the form:

We substitute the point
and find b:

Thus, the equation is:
