Answer:
26x+61
Step-by-step explanation:
Answer:
6.28
Step-by-step explanation:
1/2 x 3.14 x 2^2 = 6.28
We analyze the linear function to find that it has equation
![y=x](https://tex.z-dn.net/?f=y%3Dx)
. Drawing the line, we find that it
will intersect the circle at negative and positive x-coordinates.We can prove this by
substituting ![y=x](https://tex.z-dn.net/?f=y%3Dx)
into the given equation:
![x^2+x^2=36](https://tex.z-dn.net/?f=x%5E2%2Bx%5E2%3D36)
![2x^2=36](https://tex.z-dn.net/?f=2x%5E2%3D36)
![x^2 = 18](https://tex.z-dn.net/?f=x%5E2%20%3D%2018)
![x = \pm 3\sqrt{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cpm%203%5Csqrt%7B2%7D)
Hence,
![x = 3\sqrt{2}](https://tex.z-dn.net/?f=x%20%3D%203%5Csqrt%7B2%7D)
or
![-\sqrt{2}](https://tex.z-dn.net/?f=-%5Csqrt%7B2%7D)
, so there are both positive and negative values for
![x](https://tex.z-dn.net/?f=x)
.
