To find an inverse function:
1. Write the function.
2. Replace f(x) with y.
3. Switch x and y.
4. Solve for y.
5. Replace y with
Now let's follow the steps above and do it.
1. f(x) = 4x
2. y = 4x
3. x = 4y
4. y = x/4
5.
Answer:
im pretty sure its 27.
Step-by-step explanation:
if g(x) = 20 then the new problem is 20=x-7
20=x-7 . add 7 to both sides
+7=+7 . +7 cancels out the -7
27=x . <<<answer
Answer:
Step-by-step explanation:
(1) 
Dividing both sides by 
will give us the answer:
(2) 
Subtracting both sides by 
will give us the answer:
(3) 
First let's multiply both sides by 
Now, let's divide both sides by 
to get our answer:
(4) 
Dividing both sides by will give us the answer:
A they should work on managing income what they spend and what they earn so they could spend less and make more make sense <span />
Square root of A= 7.66 ( Took the first 2 numbers after the decimal.)
Square root of B= 3.16 (Took the first 2 numbers after the decimal.)
HOPE THIS HELPS! ^_^
