What is the inverse of y= 10^x +8?
shepuryov [24]

Answer:

x = \log_{10}(y - 8), where y > 8.

Step-by-step explanation:

The question is asking for an expression for x in terms of y.

The first step is to move as many constants away from the side with x as possible. In this question, that could be done by subtracting 8 from both sides of the equation.

y - 8 = 10^{x} + 8 - 8.

y - 8 = 10^{x}.

Notice how x is in the position of an exponent. Logarithms could help move x out of that position.

For any base b > 0:

\log_{b} b^{x} = x\, \log_{b}\, b = x.

In this question, 10 would be the base. That is: b = 10.

Take the logarithm (with 10 as the base) of both sides of the equation y - 8 = 10^{x}:

  • Left-hand side: \log_{10} (y - 8).
  • Right-hand side: \log_{10} \left(10^{x}\right) = x\, \log_{10}\left(10\right) = x.

Equate both sides to find an expression for x:

x = \log_{10}(y - 8).

Answer:

159 degrees

Step-by-step explanation:

A full semicircle (or half circle) has a degrees of 180. And x is equal that semicircle so x = 180, now if we subtract 21 from 180 we get 159, so X = 159.

42=Wf×64 (what fraction)
Dmitry [639]
So basically 42=x times 64 or 42=64x where you want x to be represented as a fraction so just don't simplify as much

42=64x
divide both sdies by 64
42/64=64/64x
42/64=1x
x=42/64
simplify
42/64=21/32

the answer is 21/32 in simplest form
