Question

Determine the value of x when f(x) = 8. f(x) = 7 1 − x What is the value of x when f(x) = 8?

Answer 1

To find the value of x when f(x) = 8 for the function f(x) = 7/(1 - x), you solve the equation by isolating x and find that x = 1/8.

Step-by-step explanation:

To determine the value of x when f(x) = 8, given that f(x) = 7/(1 - x), we need to set the function equal to 8 and solve for x:

8 = 7/(1 - x)

Multiplying both sides by (1 - x) to eliminate the fraction gives us:

8(1 - x) = 7

Now, distribute the 8:

8 - 8x = 7

Subtract 8 from both sides:

-8x = -1

Finally, divide by -8:

x = 1/8

So, the value of x when f(x) = 8 is 1/8.

Answer 2

x=63

Step-by-step explanation:

If f(x)=8 and f(x)=71-x, these can be set equal to eachother

71 - x = 8

Subtract 71 from both sides to isolate the variable

- x = -63

divide both sides by -1 because the variable can not be negative

x = 63

hope this helps! :)
