Answer:
⅔
Step-by-step explanation:
slope = (-5-3)/(-14+2) = -8/-12= ⅔
Answer:
The answer are
A.
![{f}^{ - 1} (x) = \frac{x + 3}{x - 2}](https://tex.z-dn.net/?f=%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%20%3D%20%20%5Cfrac%7Bx%20%2B%203%7D%7Bx%20-%202%7D%20)
B.
![{f}^{ - 1} ( - 3) = 0](https://tex.z-dn.net/?f=%20%7Bf%7D%5E%7B%20-%201%7D%20%28%20-%203%29%20%3D%200)
Step-by-step explanation:
To find the infers we do that
![f(x) = \frac{2 x + 3}{x - 1 } \\ (x - 1)f(x) = 2x + 3 \\ xf(x) - f(x) = 2x + 3 \\ xf(x) - 2x = f(x) + 3 \\ x(f(x) - 2) = f(x) + 3 \\ x = \frac{f(x) + 3}{f(x) - 2} \\ then \: \\ {f}^{ - 1} (x) = \frac{x + 3}{x - 2} \\ then \\ {f }^{ - 1} ( - 3) = \frac{ - 3 + 3}{ - 3 + 2} = 0](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20%5Cfrac%7B2%20x%20%2B%203%7D%7Bx%20-%201%20%7D%20%20%5C%5C%20%28x%20-%201%29f%28x%29%20%3D%202x%20%2B%203%20%5C%5C%20xf%28x%29%20-%20f%28x%29%20%3D%202x%20%2B%203%20%5C%5C%20xf%28x%29%20-%202x%20%3D%20f%28x%29%20%2B%203%20%5C%5C%20x%28f%28x%29%20-%202%29%20%3D%20f%28x%29%20%2B%203%20%5C%5C%20%20x%20%3D%20%20%5Cfrac%7Bf%28x%29%20%2B%203%7D%7Bf%28x%29%20-%202%7D%20%20%5C%5C%20then%20%5C%3A%20%20%5C%5C%20%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%20%3D%20%20%5Cfrac%7Bx%20%2B%203%7D%7Bx%20-%202%7D%20%20%5C%5C%20then%20%5C%5C%20%20%7Bf%20%7D%5E%7B%20-%201%7D%20%28%20-%203%29%20%3D%20%20%5Cfrac%7B%20-%203%20%2B%203%7D%7B%20-%203%20%2B%202%7D%20%20%3D%200)
Answer:
Formula to calculate cost price if selling price and profit percentage are given: CP = ( SP * 100 ) / ( 100 + percentage profit). Formula to calculate cost price if selling price and loss percentage are given: CP = ( SP * 100 ) / ( 100 – percentage loss )
Step-by-step explanation:
this is the formula you need to use
