Is there a picture to this question or ?????
The perimeter of a 5 cm square is 20 cm, about 7.87 inches.
In figure, the line segment XY is parallel to side AC of ΔABC and it divides the triangle into two parts of equal areas. :)
recall that the vertical asymptotes come from zeroing out the denominator, thus
x + 3 = 0, x = -3 <--- our only vertical asymptote.
Answer:
![f^{-1}(x)=\frac{1}{4} x-\frac{5}{4}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Cfrac%7B1%7D%7B4%7D%20x-%5Cfrac%7B5%7D%7B4%7D%20)
Step-by-step explanation:
make
the subject:
![y=4x+5](https://tex.z-dn.net/?f=y%3D4x%2B5)
⇒ ![4x=y-5](https://tex.z-dn.net/?f=4x%3Dy-5)
⇒ ![x=\frac{1}{4} y-\frac{5}{4}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B4%7D%20y-%5Cfrac%7B5%7D%7B4%7D%20)
change y to x:
![f^{-1}(x)=\frac{1}{4} x-\frac{5}{4}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Cfrac%7B1%7D%7B4%7D%20x-%5Cfrac%7B5%7D%7B4%7D%20)
