Write an algebraic expression for the following word phrase.
8.46 less than the product of 42 and x

To solve this, we simply need to break down the problem. Doing this will yield us the correct equation.

"8.46 less than"
This shows we are going to have something subtracted by 8.46.
-8.46

"the product of"
This shows we will have a multiplication problem.
*-8.46

"42 and x"
This shows the values that we will be multiplying
42*x-8.46

Now we can simplify
42x-8.46

Using the logic above, we can see that the expression to represent the phrase is 42x-8.46.

If the graph is this one:http://assets.openstudy.com/updates/attachments/556b7614e4b0ae03fc84336f-haileyjcaroen-1433105982090...
Then the correct features that are present in this polar graph are Symetry about the polar axis= 0 and Symetry about the pole (0,0), so B and C. Hope this helps.
