11.
Given:
![y=x^2](https://tex.z-dn.net/?f=y%3Dx%5E2)
Differentiate with respect to x, we get
![\frac{dy}{dx}=2x](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D2x)
The given point is (3,9)
Substitute x=3 in the derivative, we get
![\frac{dy}{dx}=2\times\times3=6](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D2%5Ctimes%5Ctimes3%3D6)
Hence the slope is 3.

Given:
![y=x^2+4](https://tex.z-dn.net/?f=y%3Dx%5E2%2B4)
Differentiate with respect to x, we get
![\frac{dy}{dx}=2x+0](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D2x%2B0)
The given point is (0,4)
Substitute x=0 in the derivative, we get
![\frac{dy}{dx}=2(0)+0=0](https://tex.z-dn.net/?f=%5Cfrac%7Bdy%7D%7Bdx%7D%3D2%280%29%2B0%3D0)
Hence the slope is 0.
X+(x+10)=104
2x=94
x=47
x+10=57
Your answers are 47 and 57. Hope this helps!
