Answer:
Step-by-step explanation:
760·0.5^(t/9) = 19
0.5^(t/9) = 19/760
2^(-t/9) = 0.025
-t/9 = log₂(0.025)
t = -9log₂(0.025) = 47.9 minutes
The equation of the line has the form: y = ax+b parallel to the line y = -2x + 7
=> a= -2
Passes through (4,1) => x=4, y=1
Substituting into the equation:
1= -2x(4) + b => b= 9
=> y= -2x + 9
