Answer:
A) One hundred random students
Step-by-step explanation:
53/4 as a mixed number is 13 1/4
1) f(x)=7x-8 and g(x) = 4-x: find f(g(x))
f(g(x)) = [7(4-x) -8] = -7x+20
Domaine of f(x)/g(x) = (7x-8)/(4-x)
this function is valid for all x≠4
<u />domaine = ]- ∞,4[ ∪ ]4, + ∞[<u />
3+4=7 M+P=7 That’s your answer
