45% is 45/100, divide that by 5 and you get 9/20

Answer: D) h(x) = (1/4)x</h3>
This is the same as h(x) = x/4
In decimal form, it would be h(x) = 0.25x
=============================================
Explanation:
Inverses undo the original function. The original function tells us to take any input (x) and multiply by 4 to get the output y = f(x) = 4x
To get the inverse, we reverse the operation applied here. The opposite of multiplication is division. So we'll divide by 4 instead of multiply by 4. This is why the answer is x/4 or (1/4)x
-----------
Another approach is to do the following: Replace f(x) with y. Swap x and y. Solve for y
f(x) = 4x
y = 4x
x = 4y
4y = x
y = x/4
h(x) = x/4
We end up with the same result as before.
-----------
Extra info:
For any real number x, the following two equations are true
h( f(x) ) = x
f( h(x) ) = x
Answer=15
She went to Kroger and bought food for $36.00
a turkey that cost( $1.50 per pound)
If she spent( $58.50) how many pounds was the turkey
How we got our answer was easy, first we figured she spunt 36.00 on everything else
Then we see she pays 1.50 per pound of turkey
Now we have to subtract 36 from 58.50 to figure out how much the turkey was.
We got 22.50, now we divide this by 1.50 to get our answer.
When we did that we got 15
Hope this helps!
