8.25 hours is our base number here. 1/3 of it is taken up when he stops at the gas station.
8.25, 4.125 is half of it, 2.75 is our answer for this,
8.25/3 gives you 2.75 due to 2.75 making it 5.5 when doubled and so on
so, the answer is 2 3/4 hours, D
2500 is 5% of 50000, I'm pretty sure of it.
Answer:
-8/5 = -1 and 3/5
Step-by-step explanation:
slope = change in y/change in x = (4-12)/(9-4) = -8/5 = -1 and 3/5

Answer:
C). sign chart; zeroes
Step-by-step explanation:
A function potentially changes sign at each of its <em>zeros</em> and vertical asymptotes. So, to fill out a <em>sign chart</em>, you need to determine what the sign is on either side of each of these points. You can do that using test numbers, or you can do it by understanding the nature of the zero or asymptote.
<u>Examples:</u>
f1(x) = (x -3) . . . . changes sign at the zero x=3. Is positive for x > 3, negative for x < 3.
f2(x) = (x -4)^2 . . . . does not change sign at the zero x=4. It is positive for any x ≠ 4. This will be true for any even-degree binomial factor.
f3(x) = 1/(x+2) . . . . has a vertical asymptote at x=-2. It changes sign there because the denominator changes sign there.
f4(x) = 1/(x+3)^2 . . . . has a vertical asymptote at x=-3. It does not change sign there because the denominator is of even degree and does not change sign there.
