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

_____ + 5 3/4 = 9 5/8<br>please help you will get 75 points​
LuckyWell [14K]

Answer:

3 7/8

Step-by-step explanation:

_____ + 5 3/4 = 9 5/8

x + 5 3/4 = 9 5/8

Subtract 5 3/4 from each side

x + 5 3/4 - 5 3/4 = 9 5/8 - 5 3/4

x = 9 5/8 - 5 3/4

Get a common denominator of 8

5 3/4 *2/2 = 5 6/8

x = 9 5/8 - 5 6/8

We need to borrow 1 from the 9 in the form of 8/8

x= 8 + 8/8+ 5/8 - 5 6/8

x = 8  13/8 - 5 6/8

  = 3 7/8

In the United States, a person eats more than 40,000 pounds of bread in a lifetime if she or he lives to be 80 years old. Does t
Shalnov [3]
Look at some shorter periods of time to decide whether their reasonable. Do that by simplifying the fraction. . . . . 40,000 pounds / 80 years = 4,000 pounds / 8 years = 2,000 pounds (1 ton) / 4 years = 1,000 pounds / 2 years (have you decided yet ? Well, simplify it some more) 1,000 pounds / 2 years = 500 pounds per year = almost 1 and 1/2 pounds of bread every day of your life. NOW what do you think ? Make sense ?

It would be: 0.38 / 0.25
Cancel both the decimals,

Now, it becomes too easy can be simplified by division

In short, Your Answer would be 1.52

Hope this helps!
