Answer:
please send the whole question.
actually the value of f(x) is missing
<span><span>Molly: 105 x 05/02 = 42</span>
Kim: 105-42</span> = 63
<span> Laura: 385-105 = 280
280 x 100/385</span><span> = 72%
Donc Laura obtient 72</span>%
Answer:
B
Step-by-step explanation:
To evaluate (f ○ g)(- 4), first evaluate g(- 4) then substitute this value into f(x)
g(- 4) = 3(- 4) - 5 = - 12 - 5 = - 17, then
f(- 17) = 4(- 17) + 7 = - 68 + 7 = - 61 → B
Answer:
