The graph shows the amount of a medicine , in milligrams, remaining in a patient’s body ℎ hours after receiving an injection. The amount of the medicine decreases exponentially. a. By what factor did the medicine decrease in the first hour and a half? Explain how you know.
b. By what factor did the medicine decrease in the first half hour? What about in
the first hour? Explain how you know.
c. Write an equation relating , the number of milligrams of the drug in the
patient’s body, and ℎ, the number of hours since the injection.

step-by-step explanation: where's the phrase?

b) well because you get well

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
