Can someone check my work on these please? 1. find a point c satisfying mean value theorem for f(x) = 1/x on [1,4]

shouldn't this be c = -4 ?

2. determine the intervals for which the function f(x) = x^2 + 8ln(x) - 10x is increasing

shouldn't this be on (-infinity, 1) U (4, infinity) ?

3. see the attached picture

shouldn't this be (-infinity, -2) U (1, infinity) ?

it depends on the weather. because i have flown to seattle when it was pouring down rain and there was one time i flew to ohio when it was snowing hard. whats your situation.

step-by-step explanation:

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
