The percentage of alcohol in a person's bloodstream t hr after drinking 8 fluid oz of whiskey is given by the function below. a(t) = 0.18te-0.3t (0 ≤ t ≤ 12)at what time after drinking the alcohol is the percentage of alcohol in the person's bloodstream at its highest level? (round your answer to two decimal places.)t = hrwhat is the level? (round your answer to three decimal places.) %

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

the answer, i believe is y-8=1(x+4)
