Let x- intercept represents time
Let y-intercept represents population
Let 1990 represent initial year
Points are (0,14.2)(10,12.4)
slope m=
=
General linear equation
y= mx+b --------------(i)
here m is slope and b is intercept
plug the 1st point in equation
14.2= -0.018(0) + b
b=14.2
y= 0.018x + 14.2
replace y with p(t) and x with t
p(t) = -0.018t + 14.2
Answer:
<h2>0.67</h2>Step-by-step explanation:
Distribute 5 through the parentheses
Distribute 4.7 through the parentheses
Move ' 4.7 y ' to L.H.S and change it's sign
Move constant to R.H.S and change it's sign
Collect like terms
Calculate
Divide both sides of the equation by 0.3
Calculate
Hope this helps...
