Im not sure but
(sarah + tara)/2 = 8
(20 + tara)/2 = 8
20 + tara = 16
tara = 4hours ?? it doesn’t make logical sense but this is the only way i can think of
sorry if this wasn’t helpful ;-;
Answer:
3
Step-by-step explanation:
replace all x variables with 1 and solve that equation ; f(x)=x-8 so.... f(x) = 1-8
there for f(1)=-7
now, add -7 and 10 for your answer:
f(1)+10= 3
This isn't a question. What is the question?
