Hello,
(9*140-180)/8=147.5

Answer:
(3rd listed choice) Paula's notes are incorrect. Step 4a should be "If the result does not define y as a function of x, then f does not have an inverse," and step 4b should be "If the result defines y as a function of x, then f has an inverse."
Step-by-step explanation:
If f(y) = x can be solved for a relation for y that is a function, then f(x) has an inverse. It will be the function defined by y.
Answer:
Step-by-step explanation:
Choice A
Log 10 = 1.
So A is actually right, although it does not look it.
log(20 * x^5 ) - 1 is correct.
Choice B
Log(x^5 * 20 / 10)
log(2 x^5)
Choice B is also correct
Choice C is not correct, or if it is, I don't know how to get it. You need the 20 in there somewhere.
No! Dis not correct. The 2 is not raised to the 5th power.
And E is not correct. I'm not sure how they got it. Even + 1 is not correct. It should be -1 if that is how it is to be done.
