Question:
Which is equivalent to  after it has been simplified completely?
 after it has been simplified completely?
Answer:

Step-by-step explanation:
Given

Required
Simplify
We start by splitting the square root

Replace 180 with 36 * 5

Further split the square roots


Replace power of x; 11 with 10 + 1

From laws of indices; 
So, we have


Further split the square roots

From laws of indices; 
So, we have



Rearrange Expression


From laws of indices; 
So, we have



<em>The expression can no longer be simplified</em>
Hence,  is equivalent to

f(-1) = -11 and f(3) = -3 . these functions are true . 
What does a math function mean?
- A relationship between a group of inputs and one output each is referred to as a function.
-   A function is an association between inputs in which each input is connected to precisely one output.
-  A domain, codomain, or range exists for every function. f(x), where x is the input, is a common way to refer to a function.
- In mathematics, a function is an expression, rule, or law that establishes the relationship between two variables (the dependent variable).
given function  f(x) = 2x - 9
    f(-1) = -11 ⇒ x = -1 put in function
                        f( -1 ) = 2 * -1 - 9  ⇒ - 11
     f(2) = 5   ⇒ x = 2 put in function
                     f( 2 ) = 2 * 5 - 9 = 1
     f(3) = -3  ⇒  x = 3 put in function
                      f ( 3 ) = 2 * 3 - 9 = -3
        f(-3) = 15   ⇒  x =  -3 put in function
                      f( -3) = 2 * -3 - 9 = - 15

Answer:
B
Step-by-step explanation:
1.6/0.2=8
10⁵-10²=10³
 
        
             
        
        
        
5x-7y=14 
-5x -5x
^
Subtract 5x from both sides
-7y=-5x+14
Divide by -7 by all of the numbers
y=-5/7x-2
