Medicine Erika takes 400 mg of Tylenol
for a headache. Every hour, the
amount of medicine left in her
bloodstream is divided by 2.
x=the number of hours since she
has taken the Tylenol
y = the amount of Tylenol
remaining in her bloodstream
Reasoning:

because she is getting a lot of the yummy drugs

Im sorry I dont know he anwser but I want to make you laugh if your stressed

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
