Where’s the problem where it explains what’s she is subtracting?
Let y = f(x)
y = ln(3x)
Exchange place with x and y.
x = ln(3y)
Solve for y.
y = (e^x)/3
Replace y with the inverse notation.
f^(-1) x = (e^x)/3
Done.
<span>C. Subtraction Property of Equality; Multiplication Property of Equality
For the first one, you are subtracting 7 from both sides (step b), to help isolate the y
since you are both subtracting, and "both sides" (meaning there is a equal sign) it is <em>Subtraction Property of Equality.</em>
For the second one, you are multiplying 2 from both sides (step d), to help isolate the y
since you are multiplying, and "both sides" (meaning there is a equal sign), it is <em>Multiplication Property of Equality</em>

P(A) = 0.993 is the probability of event A
_
P(A) is the probability of not A (note that I am trying to place a bar over A. I hope you can see it, else it is because the editor did not show it as I intended)
Then, use the fact that the probability of A plus the probability not A is equal to 1:
_
=> P(A) + P(A) = 1
_
=> P(A) = 1 - P(A) = 1 - 0.993 = 0.007
So, the answers are:
_
1) P(A) = 0.07
_
2) Yes, A is unlikely because its probability is very low.
Answer:
72 mins
Step-by-step explanation:
12/4=3 tortillas per min
3 x 24 = 72 min to bake 24 tortillas
Hope this helps :D
