Answer:
210 orange candles
280 blue candles
Step-by-step explanation:
x = blue candles
y = orange candles
y = 0.75x
x + y = 490
x + 0.75x = 490
1.75x = 490
x = 280
280 + y = 490
y = 210
Answer:
f-1(x) = x + 12.
Step-by-step explanation:
let y = x - 12
Now find x in terms of y:
x = y + 12
so the inverse is the following ( replace y by x):
f-1(x) = x + 12.
I believe the correct answer is B. -5
