Assuming that you meant she drives 129 km everyday (her work hours are not stated) then the answer should be 3999km.
To find this, simply multiply her daily kilometers (129) by the days (31) in order to find how many she drives in the set period of time provided.
Hope this helps!
D - gasoline number of miles you drove since filling up
The slope perpendicular to an undefined slope is: 0
Example:
x = 5 is a vertical line and has an undefined slope.
The line perpendicular to it is y = <em>any value</em> which has a slope of 0.
I hope this makes sense. If not, please post the homework question so we can help you find the circumcenter.
