2. - Kevins average speed is 67.5 mph
Answer:
7b^3 + 9b^2 + 8b
Step-by-step explanation:
Combine like terms
My teacher taught me a few years ago to put like terms in the same format so they're easier to combine:
b^3 + <em>7b </em>+ <u>9b^2</u> + <em>b </em>+ 6b^3
Here I have all terms to the 3rd power bolded, all terms to the 2nd power underlined, and all terms to the 1st power italicized. That makes it easier to combine those that are similar
b^3+ 6b^3 = 7b^3
<u>9b^2</u> - remains the same
<em>7b </em>+ <em>b = 8b</em>
Now just reorder them to where the exponents are listed from greatest to least:
7b^3 + 9b^2 + 8b
Answer:

Answer:
a. No, because she will need money a year from now. Generally, stocks are long term investments. It is very unlikely that she will get a return on her investment in a year.
Step-by-step explanation:
Stocks are a riskier investment in comparison to bonds, and may pay higher interest rates, but still require the investment to "sit" for a long period of time. Like a 3 month (APY of about .50%), 6 month (APY of about .30%), 8 month (APY of about .10%), etc. bond, stocks will not grow considerably in a short amount of time.
I think that the answer is y=-x+6
