What's the value of x? 40000mg =10x g
dybincka [34]

The value of x is 4. So 40000 mg= 40 g.

Step-by-step explanation:

      The given is 40000mg = 10x g

Step:1

      Take given equation as equation (1)

                     40000 mg= 10x g.................(1)

      where, X is known value.

Step:2

      Standard value for mg to g for the purpose of conversion of units,

                      1 milligram = 0.001 gram   (or)

                      1 gram = 1000 milligram

Step:3

      From the standard data values,

                    = 40000 mg

      it converted mg to g by dividing 1000

                    = \frac{40000}{1000} g

                    = 40 g.......................(2)

Step:4

       From the Equations (1) and (2),

                 40=10x

                  x=4

Result:

       The value of x is 4. So, 40000mg = 40 g.

Which represents the inverse of the function f(x) = 4x?
zhenek [66]

Answer:

h(x) = 1/4x

Step-by-step explanation:

To find the inverse, first we rewrite the function using y instead of f(x):

y = 4x

Next we switch x and y:

x = 4y

Solve for y by dividing both sides by 4:

x/4 = 4y/4

x/4 = y

1/4x = y
