Answer:
Step-by-step explanation:
L = 2W + 5
A = LW = 63
L = 63/W
W=63/L
L = 2W + 5
63/W = 2W + 5
63 = 2WW + 5W
2WW + 5W - 63 = 0
2WW + 5W - 63 = 0
is already in quadratic equation form: ax^2 + bx + c = 0
use the quadratic formula to solve for two solutions:
x = ( -b +- sqrt( bb - 4ac ) ) / 2a
the two solutions are:
x = 9/2
x = -7
you cant have a negative solution for length so use the positive one
solve for length:
L=5+2(9/2)
L=5+18/2
L=5+9
L=14
Answer: ![f^-^1(x)=\frac{x+5}{11}](https://tex.z-dn.net/?f=f%5E-%5E1%28x%29%3D%5Cfrac%7Bx%2B5%7D%7B11%7D)
Step-by-step explanation:
To find the inverse, you replace the x with y, and y with x.
[add 5 on both sides]
[divide both sides by 11]
![\frac{x+5}{11} =y](https://tex.z-dn.net/?f=%5Cfrac%7Bx%2B5%7D%7B11%7D%20%3Dy)
![f^-^1(x)=\frac{x+5}{11}](https://tex.z-dn.net/?f=f%5E-%5E1%28x%29%3D%5Cfrac%7Bx%2B5%7D%7B11%7D)
