Answer:
It refers to a numerical or constant quantity placed before and multiplying the variable in an algebraic expression.
Answer:

Step-by-step explanation:
Given:
Width of average grain of salt is, 
Width of Rhinovirus is, 
Now, expressing each width in scientific notation form, we get:

Now, in order to get how many times 'W' is wider than 'w', we divide the two widths. This gives,

Therefore, the grain of salt is
wider than Rhinovirus.
Step 1: Find the slope:

This gives you
, but we need to find b.
To find b, substitute in one (x,y) pair and it doesn't matter which one. I'll go with (4,-2):
![\begin{aligned}-2&=-\dfrac{3}{2}(4)+b\\[0.5em]-2&=-6+b\\[0.5em]4&=b\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D-2%26%3D-%5Cdfrac%7B3%7D%7B2%7D%284%29%2Bb%5C%5C%5B0.5em%5D-2%26%3D-6%2Bb%5C%5C%5B0.5em%5D4%26%3Db%5Cend%7Baligned%7D)
Now take that b-value and plug in into the slope-intercept form:

It's always a good idea to toss in the other x-value from the other point, to make sure it checks out.

Answer:
Step-by-step explanation:
$ 86,000 lies in the category $84201 - $ 160725
Tax = 14,382.50+ 24% of the amount over $84,200
Amount over $84,200= 86,000 - 84,200 = $1,800
Tax for the amount $ 1,800 =24% * 1800 = 0.24 * 1800
= $ 432
Tax for the amount $86,000 = 14382.50 + 432
=$ 14814.50
