Replace f(x) with x⁸

1) f(x) + 2     →       x⁸ + 2

2) 3f(x)        →       3x⁸

3) f(-x)         →       (-x)⁸

4) f(x - 2)      →     (x - 2)⁸

5.\ \dfrac{1}{3}f(x)        →      \dfrac{1}{3}x^8

36/49 = 5/n find n. will mark for whoever answers
Crazy boy [7]

Answer:

  n = 245/36

Step-by-step explanation:

Usually, these are solved in 2 steps:

  1. eliminate fractions by multiplying by the LCM of the denominators
  2. divide by the coefficient of the variable.

Doing that, we have ...

  (49n)(36/49) = (49n)(5/n)

  36n = 49·5 = 245 . . . . . simplify

  n = 245/36 . . . . . divide by the coefficient of n

_____

Another way to do these is to rewrite the proportion with both sides inverted:

  49/36 = n/5

Now, all you need to do is multiply by 5.

  n = 5(49/36) = 245/36

__

Or, you can do both of the original steps at the same time:

  (49n/36)(36/49) = (49n/36)(5/n)

  n = (49·5)/36 = 245/36
