The answer is a= -4.181818
Answer is 8
Work Shown:
f(x) = sqrt(5*x + 4)
f(12) = sqrt(5*12 + 4) ... replace every x with 12
f(12) = sqrt(60 + 4)
f(12) = sqrt( 64 )
f(12) = 8

Answer:
The most reasonable is 2 h
Step-by-step explanation:
If you see the graph is decreasing in hours while is increasing in years. When a person is 45 years the amount of daily physical activity is 3 hours, so a person that is 50 years needs to do less than 3 hours a day and the only option less than 3 hours is 2 hours.
J is your answer.
Slope is rise over run + your Y intercept.
Your y- intercept is the point in the graph in which the line passes through, the line passes through -2, so you know -2 is going to be your answer at the end. And slope is rise/run.
From one point to another, you rise 1 time , and run over 3 so you know your answer is
y = 1/3x - 2
hope this helps :)
