Answer:
Umm I'm not entirely sure but I think its the last one
To put it into an equation, it would be:
340 = 2x - 100
with x being the amount of sophomores at BHSS.
Solve it:
340 + 100 = 2x
2x = 440
x = 220
The number of sophomores at BHSS is 220.
(B)
if <em>f</em>(a) = K, then that means <em>f </em>sends (a) to (K).
the inverse function, <em>f</em>-1, goes back where you started, so <em>f</em>-1 <em />sends (K) to (a).
<em>f</em>-1(K) = a.
Answer:
15
Step-by-step explanation:
18-x=3
18-3=x
18-3=15
233 1/3
you start with .3x = 70, as this is the sentence given, solving for x.
divide both sides by .3, and you get x
