3rd one seems to be the correct answer
5x(x+6)=-50
X(x+6)=-10
X square +6x=-10
(X+3) square=-10-9
(X+3) square=-19
So this equation has no solution
Answer:
Step-by-step explanation:
Given that the number of asthma sufferers in the world was about 84 million in 1990 and 130 million in 2001.
Let N represent the number of asthma sufferers (in millions) worldwide t years after 1990.
a) If linear function let us assume 1990 as base year 0 then 2001 would be year 11
When written as ordered pairs year and asthma sufferers in millions we have
(0,84) and (11,130) lie on the line
Using two point formula equation of line is
Slope = 46/11
b) When exponential we have

Use N(11) = 

c) In 2010, t = 20
Linear y(20) = 
When exponential
N(20) =
