Always use the inverse (opposite) operation. Ex. is 2x+4=10.
First subtract 4, and then divide by 2.
actually reverse of order of operations to solve.

Answer:
y=-1/4x-6
Step-by-step explanation:
y intercept is -6 and slope is -1/4
point slope is y-y1=m(x-x1)
you can use and point. i am using (0,-6)
y--6=-1/4(x-0)
y+6=-1/4x
-6 -6
y=-1/4x-6
Answer:
Time(t) = 11.61 hours (Rounded to two decimal place)
Step-by-step explanation:
Given: The antibiotic clarithromycin is eliminated from the body according to the formula:
......[1]
where;
A - Amount remaining in the body(in milligram)
t - time in hours after the drug reaches peak concentration.
Given: Amount of drug in the body is reduced to 100 milligrams.
then,
Substitute the value of A = 100 milligrams in [1] we get;

Divide both sides by 500 we get;

Simplify:

Taking logarithm both sides with base e, then we have;

[ Using
]
or

[using value of
]
then;

Simplify:
t ≈11.61 hours.
Therefore, the time 11.61 hours(Rounded two decimal place) will pass before the amount of drug in the body is reduced to 100 milligrams
