Answer: -2/7
This value is a fraction.
----------------------------------
Work Shown:
The first two rows in the table produce these two points (x1,y1) = (-14,8) and (x2,y2) = (-7,6)
So, x1=-14, y1=8, x2=-7, and y2=6
Plug these four values into the slope formula and simplify
m = (y2 - y1)/(x2 - x1)
m = (6 - 8)/(-7 - (-14))
m = (6 - 8)/(-7 + 14)
m = -2/7
First you would convert it to a fraction. 9/100
Once you do that you divide the numerator, which is 9 by the denominator, which is 100.
Then we get our answer, 0.09
Answer: 
Step-by-step explanation:
Given
It takes 20 min and 30 min for a person and his friend to paint a wall individually i.e.
In 1 min they cover 
part and 
part of wall respectively.
If the work together, 1 minute work is
Time required will be reciprocal of it
X equals 53/11 , y equals -16/11
I think #13 is A (90 cubic meters) even though you already have that
