[ Step One ] Apply Rule - (-a) = a

[ Step Two ] Add

Using the product rule, we have
![m(x) = x W(x) \implies m'(x) = xW'(x) + W(x)](https://tex.z-dn.net/?f=m%28x%29%20%3D%20x%20W%28x%29%20%5Cimplies%20m%27%28x%29%20%3D%20xW%27%28x%29%20%2B%20W%28x%29)
so that
![m'(7) = 7W'(7) + W(7)](https://tex.z-dn.net/?f=m%27%287%29%20%3D%207W%27%287%29%20%2B%20W%287%29)
The equation of the tangent line to <em>W(x)</em> at <em>x</em> = 7 has all the information we need to determine <em>m'</em> (7).
When <em>x</em> = 7, the tangent line intersects with the graph of <em>W(x)</em>, and
<em>y</em> = 4.5 + 2 (7 - 7) ==> <em>y</em> = 4.5
means that this intersection occurs at the point (7, 4.5), and this in turn means <em>W</em> (7) = 4.5.
The slope of this tangent line is 2, so <em>W'</em> (7) = 2.
Then
![m'(7) = 7\cdot2 + 4.5 = \boxed{18.5}](https://tex.z-dn.net/?f=m%27%287%29%20%3D%207%5Ccdot2%20%2B%204.5%20%3D%20%5Cboxed%7B18.5%7D)
First you should find the discount so you can say:
10/100 = ?/82
so ? is your discount and ? is equal to:
? = 82*10/100 = 8.2
so your discount is $8.2 and your sale price will be:
$82 - $8.2 = $73.8 :)))
I hope this is helpful
have a nice day
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 10
Answer:
18. Its 2 meters.
19. Its 0.2 grams
20. Its 1,920
Step-by-step explanation:
When you convert 200 centimeters to meters its 2.
When you convert 2,000 milligrams in grams its 0.2
15% of 12, 800 is 1,920
Hope this helps:)
