Answer:
Option C is correct
Step-by-step explanation:
The two triangles are similar if there sides are proportional to each other
So, In Triangle ABC and Triangle DEF
AB/DE=BC/EF=AC/FD
according to definition of similar triangles.
We are given AC = 8
and FD = 4
So, AC/FD = 8/4 = 2/1
or 2:1
So, Option C is correct

Answer:
Rewriting
without an exponent we get 
Step-by-step explanation:
We need to rewrite the following without an exponent. 
We need to solve the exponent to find the result.
We know the exponent rule: 
Now using this rule to solve the equation:

So, Rewriting
without an exponent we get 
To get the inverse "relation" of an expression, we first off, do a quick switcharoo of the variables, and then solve for "y", so let's proceed,

and yes, the domain for the range 0 ⩽ x
