@meerkat18 can you confirm?

clara is taking a medicine for a common cold. the table below shows the amount of medicine f(t), in mg, that was present in clara's body after time t: t (hours) 1 2 3 4 5 f(t) (mg) 236.5 223.73 211.65 200.22 189.41 heidi was administered 300 mg of the same medicine. the amount of medicine in her body f(t) after time t is shown by the equation below: f(t) = 300(0.946)t which statement best describes the rate at which clara's and heidi's bodies eliminated the medicine?

clara's body eliminated the antibiotic faster than heidi's body.
clara's body eliminated the antibiotic at the same rate as heidi's body.
clara's body eliminated the antibiotic at half of the rate at which heidi's body eliminated the antibiotic.
clara's body eliminated the antibiotic at one-fourth of the rate at which heidi's body eliminated the antibiotic.

step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
