Using the product rule, we have

so that

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

C by AA- bc 180 degrees in a triangle
Nine thirds? If so its would be 9/3 / 1/3?
The answer would be 1/3 / 1/3+1 making it 2/3
Im not sure so dont take my word
Answer:
-1.5
Step-by-step explanation:
Answer:
D = - 9
Step-by-step explanation:
D - 7 = -18
D - 7 + 7 = -18 + 7
D = -9
