C= (3, -5) aND D= (6, 0)
y-y1 = m (x -x1).
i.e. if x1, y1 = 3, -5 and x2, y2 = 6,0 then#
y- (-5) = m(x - 3), so all we are missing is the slope:
Y2 -y1
--------------- = m (the slope)
x2 -x1
0-(-5)
------- = 0+5 /3 = 5/3
6 - 3
therefore equation of line is y+5 = 5/3 (x - 3)

Answer:
(x - 9)(x + 9)
Step-by-step explanation:
x² - 81 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), then
x² - 81
= x² - 9²
= (x - 9)(x + 9)
28% is 28/100 as a fraction but the simplest form is 14/50 and it can be simplified to 7/25. the decimal is 0.28
fraction is 7/25
decimal is 0.28
Answer: 10
Step-by-step explanation:
Given : The American Lung Association stated that approximately 1 out of every 20 deaths in the US last year was from lung cancer.
Then, the proportion of death will be :_
Now, If there are 200 students in a class, then the expected number of persons die from lung cancer :-
Hence, we expect the number of persons die from lung cancer =10
