Evaluate each expression individually and then combine like terms:
5 log₄(x²) = 5 = 5 = 5 = 5 log₂x = log₂x⁵
4 log₂(x) = log₂(x)⁴ = log₂(x⁴)
**********************************************
log₂(2x + 1) - 5 log₄(x²) + 4 log₂(x)
= log₂(2x + 1) - log₂x⁵ + log₂(x⁴)
= log₂[(2x + 1)*(x⁴) ÷ x⁵]
= log₂
= log₂
7 days or more. At 7 days, the total cost of daily passes comes to $651 and with the season pass and the daily $25 cost of skis after 7 days, it comes to $625.
1. A or D
2. B or D
3. 16 liters*0.78 = 12.48 liters
0.25x + 12.48 = 0.41(16+x)
0.25x + 12.48 = 6.56 +0.41x
5.92 = 0.16x
x = 5.92/0.16 = 37 liters
4. 8 liters
5. 7 liters
Factor the numerator and denominator and cancel the common factors.
The answer would be 1/4
