Basically the question is asking YOU when you hear “system of equations” what do you think about it - what do you already know about system of equations. Basically. Btw enjoy this picture.
Answer:
![\left(g/f\right)\left(x\right)=\frac{x}{4}-\frac{1}{16}-\frac{79}{16\left(4x+1\right)}](https://tex.z-dn.net/?f=%5Cleft%28g%2Ff%5Cright%29%5Cleft%28x%5Cright%29%3D%5Cfrac%7Bx%7D%7B4%7D-%5Cfrac%7B1%7D%7B16%7D-%5Cfrac%7B79%7D%7B16%5Cleft%284x%2B1%5Cright%29%7D)
Step-by-step explanation:
![f(x)=4x+1](https://tex.z-dn.net/?f=f%28x%29%3D4x%2B1)
![g\left(x\right)=x^2\:-\:5](https://tex.z-dn.net/?f=g%5Cleft%28x%5Cright%29%3Dx%5E2%5C%3A-%5C%3A5)
As
(g/f)(x) = g(x) / f(x)
![=\:\frac{x^2\:-\:5}{4x+1}\:\:\:\:\:\:](https://tex.z-dn.net/?f=%3D%5C%3A%5Cfrac%7Bx%5E2%5C%3A-%5C%3A5%7D%7B4x%2B1%7D%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A)
![=\frac{x}{4}+\frac{-\frac{x}{4}-5}{4x+1}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bx%7D%7B4%7D%2B%5Cfrac%7B-%5Cfrac%7Bx%7D%7B4%7D-5%7D%7B4x%2B1%7D)
![=\frac{x}{4}-\frac{1}{16}+\frac{-\frac{79}{16}}{4x+1}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bx%7D%7B4%7D-%5Cfrac%7B1%7D%7B16%7D%2B%5Cfrac%7B-%5Cfrac%7B79%7D%7B16%7D%7D%7B4x%2B1%7D)
![=\frac{x}{4}-\frac{1}{16}-\frac{79}{16\left(4x+1\right)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bx%7D%7B4%7D-%5Cfrac%7B1%7D%7B16%7D-%5Cfrac%7B79%7D%7B16%5Cleft%284x%2B1%5Cright%29%7D)
Therefore,
![\left(g/f\right)\left(x\right)=\frac{x}{4}-\frac{1}{16}-\frac{79}{16\left(4x+1\right)}](https://tex.z-dn.net/?f=%5Cleft%28g%2Ff%5Cright%29%5Cleft%28x%5Cright%29%3D%5Cfrac%7Bx%7D%7B4%7D-%5Cfrac%7B1%7D%7B16%7D-%5Cfrac%7B79%7D%7B16%5Cleft%284x%2B1%5Cright%29%7D)
Answer:
2
Step-by-step explanation:
If A = (2, 3) then a dilation of scale factor 2 means that the x and y coordinates are multiplied by 2, so x = 2 x 2 = 4 and y = 3 x 2 = 6, so A' = (4, 6)
