Answer:
C: x = 7
Step-by-step explanation:
The easiest way to do this is to simply try all of the x-vales given as options.
Option 1: x = -1
Since
, we'll use the first equation.

As we can see, g(-1) is not -4.
Option 2: x = 3
Since
, we'll use the 2nd equation.

Not -4.
Option 3: x = 7
Since
, we'll use the 3rd equation.

Tada! We have found a number such that g(x) = -4, it is 7. Since we only need to find a number, not all numbers, we don't have to check the last option. However, if you're curious:
Option 4: x = 4
Since
(less than <em>or equal to</em>), we'll use the 3rd equation.

Answer:
1
--------- = x
1000
Step-by-step explanation:
Copy down y = 10x.
Then substitute 1/100 for y:
1
-------- = 10x
100
Divide both sides by 10 to isolate (solve for) x:
1
--------- = x
1000
