Answer:
Step-by-step explanation:
Applying the chain rule
Then it becomes
In x=0
![\frac{d[tex]f'(0)=-f'(0)\\f'(0)+f'(0)=0\\2f'(0)=0\\](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5Btex%5Df%27%280%29%3D-f%27%280%29%5C%5Cf%27%280%29%2Bf%27%280%29%3D0%5C%5C2f%27%280%29%3D0%5C%5C)
f}{dx} =-\frac{df}{dx}[/tex]
Then
I think that the answer that is highlighted in blue is correct. I am not sure for this one. But, “both the table and graph are proportional” seems correct.
Answer:
2s + t = 23.5
Step-by-step explanation:
There are two types of shortboards:
Let the width of a standard shortboard be represented by s.
Similarly, Let the width of a technical shortboard be represented by t.
As per the given information: total width of two standard shortboards
and a technical shortboard is 23.5 inches.
Representing it as an equation in terms of the variables defined:
2s + t = 23.5
The answer is 3. 1/3(x-5)= -2/3. Multiply by 3 on both sides. Add five and you get 3
