Examples of rational numbers :
1, 1/2, 3/4 , 5 , 6, 15/8 etc
Rational numbers are numbers which can be written as fraction as also that the numerator and denominator are whole examples.
Example 5 can be written as fraction in the form of 5/1.
cubic means 3 so there is a total o 3 roots
there is 1 real zero ( where the line crosses the x axis) the other 2 would be complex zeros
Answer is D
R2-4r-77 = (r-11)(r+7)
r has to be greater than 11 in order for the formula to represent the area of a rug since a side length cannot be less than or equal to 0.
Just divide 78 with 11, 7.090909090909091.
I can't be entirely sure what you want to "do" about the slope,
but here is how to FIND it if you have the line on the graph:
-- You pick two points on the graph line.
-- Find the difference in 'y' between the two points.
-- Find the difference in 'x' between the two points.
-- The slope of the line between the two points is
(the difference in 'y')
divided by
(the difference in 'x') .
-- If the line on the graph is a straight line, then
the slope is the same everywhere on it.
