Answer:
The inverse will be:
Step-by-step explanation:
In order to find the inverse of the equation, we do a variable change, since we are finding the inverse, :
Now solve for y'.
First add 4 in both sides of the equation and change to the left y'.
= x + 4
Second divide by 9
/9 = (x + 4)/9
= (x + 4)/9
Now you will have to clear y, with the square root.
![[tex]y'^{\frac{2}{2}} = \sqrt{x + 4} / \sqrt{9}](https://tex.z-dn.net/?f=%5Btex%5Dy%27%5E%7B%5Cfrac%7B2%7D%7B2%7D%7D%20%3D%20%5Csqrt%7Bx%20%2B%204%7D%20%20%2F%20%5Csqrt%7B9%7D)

Simplifying terms
You can check the answer by doing the evaluation of the following equation:
(f o 
) (x)
substitute the equation for y' or inverse function
f(
)
Now substitue the value into f(x)
You will have
=x

I'm pretty sure it is the answer but if it isn't then sorry
Answer:
Step-by-step explanation:
If we want to convert 
into a radical simplified, we need to find two numbers that multiply to be -50 and one of them can be squared.
The square root of -25 is 5i.
So:
Hope this helped!
Answer:
4) A
5) E
Step-by-step explanation:
#4
Cross multiply the equation and you get:
Since 
is the same thing as 
, you can change the equation into 
Cancel out the y on the top and bottom and you get 1/10
#5
, simplify and you get 
so x=15
is equal to 
after you plug in x, and that is equal to 9
Answer:
x^2 +3x -504
Step-by-step explanation:
Sort of do what you'd do to solve but in reverse. You need 21 for a zero, so the binomial factor would be (x-21) since if you set that = to zero you'd get 21. Same for -24. The binomial factor would be (x+24) since that would give you -24. Now that you have the two binomials, you can just multiply them and get the quadratic. :)
