Answer:
−3m + 3
Step-by-step explanation:
F(x) = 2lnx +c so 5 = 1 +c after substitution.
Means c = 4 and f(x) = (2 lnx) +4 {NOT 2 ln(x+4)}
And so f(e) = 2+4=6.
So 6 is the answer
Answer:
188 = 46x + 73
It took 2 1/2 or 2.5 hours to complete.
Step-by-step explanation:
There is a one time cost of 73 for the parts, but the hours will be 46 per hour. I know the total cost, so we need to solve for x which is the hours.
188 = 46x + 73 Subtract 73 from both sides of the equation
115 = 46x Divide both sides of the equation by 46
2.5 = x
