Your answers would be -5 , -4
Step-by-step explanation:
let's write this properly :
f(x) = x³
g(x) = (x - 7)³ + 9
this translation means that every point of f(x) is shifted up by 9 units (by the "+ 9" term), and shifted right by 7 units (the " x - 7" term means that for every x the original result of x-7 happens, so, 7 units "later" or more to the right than originally).
so, the original (0, 0) point corresponds to (7, 9).
1. Answer: 60 minutes
<u>Step-by-step explanation:</u>
Faucet A: 140 milliliters/min = 0.140 liters/min
Faucet B: 100 milliliters/min = 0.100 liters/min
Let x represent the amount of time
Faucet A + Faucet B = Full fish tank
0.140x + 0.100x = 14.4
0.240x = 14.4
x = 60

2. Answer: 40 minutes
<u>Step-by-step explanation:</u>
Quantity currently in tank: 4.8 liters
Water In: 150 milliliters/min = 0.150 liters/min
Water Out: 270 milliliters/min = 0.270 liters/min
Let x represent the amount of time
Qty in tank + In - Out = Empty fish tank
4.8 + 0.15x - 0.27x = 0
- 0.27x = -4.8
x = 40
