Answer:
The one at the bottom is "Neither"
The one that begins with (-4,14) is exponential.
The one that begins with (-3, 8) is a linear
Step-by-step explanation:
1/5 becuase if you multiply by 5, it has to be 1, which means it has to be 1/5
Answer:
![(2,3)](https://tex.z-dn.net/?f=%282%2C3%29)
Step-by-step explanation:
The first equation is ![x+y=5](https://tex.z-dn.net/?f=x%2By%3D5)
The second equation is ![y=\frac{1}{2}x+2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B2%7Dx%2B2)
When we graph these two equations, <em>they will meet at a point which represent the solution of the two equations</em>.
We can solve the two equations simultaneously to determine their point of intersection.
Let us substitute the second equation into the first equation to get;
![x+\frac{1}{2}x+2=5](https://tex.z-dn.net/?f=x%2B%5Cfrac%7B1%7D%7B2%7Dx%2B2%3D5)
Multiply through by 2 to get;
![2x+x+4=10](https://tex.z-dn.net/?f=2x%2Bx%2B4%3D10)
Group similar terms to obtain;
![2x+x=10-4](https://tex.z-dn.net/?f=2x%2Bx%3D10-4)
Simplify;
![3x=6](https://tex.z-dn.net/?f=3x%3D6)
Divide both sides by 3;
![\Rightarrow x=2](https://tex.z-dn.net/?f=%5CRightarrow%20x%3D2)
Put
into the second equation;
![y=\frac{1}{2}(2)+2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B2%7D%282%29%2B2)
![\Rightarrow y=1+2](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D1%2B2)
![\Rightarrow y=3](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D3)
Therefore the graphs of the two functions intersect at (2,3)
