Hi , the answer is -1 , because -1 is the number that is closest to zero.
Given the endpoints of our diameter, we can use the distance formula to find the distance between the points.
Distance Formula:

(
and
are the x-values of the coordinates and
and
are the y-values of the coordinates)
Inserting our values into the distance formula we can find the length of the diameter:



The diameter of our circle is 6, or choice C.
Line up the decimal point to each number in order from left to right and subtract to get the difference which should be -0.248
Bob has 2/3 of a pecan pie. His friends gave him 4 times as much pecan pie as he had before. How much pecan pie does he have now?
X = 0
X=- 3 1/3 or x= -3.3
