Answer:

x -y +1 =0

Step-by-step explanation:

x - y + 1 = 0

(3,4)

so when x = 3 , y must equal to 4

3 - y + 1 = 0

move y to the other side

y = 3 + 1

y= 4

Which of the following are solutions to | x-1|= 5x + 2 ? Check all that apply.
agasfer [191]

By definition of absolute value, if x-1\ge0, then |x-1|=x-1, so

|x-1|=5x+2\implies x-1=5x+2\implies4x=-3\implies x=-\dfrac34

On the other hand, if x-1, then |x-1|=-(x-1)=1-x, and

|x-1|=5x+2\implies1-x=5x+2\implies6x=-1\implies x=-\dfrac16

Let a = x^2 + 4. Rewrite the following equation in terms of a and set it equal to zero. ( x^2 + 4 )^2 +32 = 12x^2 + 48
Aleks04 [339]
Answer:  In the resulting equation:  " a² - 12a + 32 = 0 " ;
________________________________________________________
  The "coefficient" of the "a" term is:  " - 12" . 
________________________________________________________
  The "constant" is:  " 32 " .
________________________________________________________

Explanation:

________________________________________________________

Let:   "a = x² + 4 " .

Given:  (x² + 4)²  + 32  =  12x² + 48  ; 
______________________________________________________

Factor:  "12x² + 48" into " (x² + 4) " ;

"12x² + 48"  =  12 (x² + 4) " ;
______________________________________________________

Given:    (x² + 4)²  + 32  =  12x² + 48 ; 

rewrite as;  "a² + 32 = 12a " ; 

Subtract "12a" from each side of the equation; 

"a² + 32 - 12a = 12a - 12a ;
 
to get:

" a² - 12a + 32 = 0 " .
___________________________________________________
The coefficient of the "a" term;  that is:

The "coefficient" of " -12a" ;  is:  "- 12" . 

The constant is:  "32<span>" .

What are the domain and range of the function f(x) = x^4-2x^2-4 ?
tatuchka [14]

Answer:

Think about what domain and range is. Domain is the x and range is the y.

Step-by-step explanation: What values of x can you put in this function? Is there any number you cannot use?? Then what y's will you get back? The best way to find out might be to graph it to look. Since it is an even function whose ends go up, all the y's will be greater than or equal to the y value of the vertex.
