Answer:

x + y = 2 ,  y = x 2 − 4 x + 4

Replace all occurrences of  

y

with  x 2 − 4 x + 4

in each equation.

x 2 − 3 x + 4 = 2 y = x 2 − 4 x + 4

Solve for  

x

in the first equation.

x = 2 , 1 y = x 2 − 4 x+ 4

Replace all occurrences of  

x  with  2

in each equation.

y=0 x = 2

Replace all occurrences of  x

with  1

in each equation.

y = 1 x = 1

The solution to the system is the complete set of ordered pairs that are valid solutions.

( 2 , 0 ) ( 1 , 1 )

The result can be shown in multiple forms.

Point Form:

( 2 , 0 ) , ( 1 , 1 )

Equation Form:

x=2 , y = 0 x = 1 , y = 1

Step-by-step explanation:

Let f(x) = -­2x ­- 7 and g(x) = ­-4x + 3. Find (f o g)(-­5)
musickatia [10]
The answer is:  [A]:  " -53 " .
_______________________________________________________
Explanation:
_______________________________________________________
Given:  

" Let f(x) = -­2x ­−<span> 7 and g(x) = ­-4x + 3.  Find (f o g)(-­5) " ;
_______________________________________________
First, find g(-5) .   g(x) = -4x + 3.  

g(-5) = -4*(-5)  + 3 = 20 + 3 = 23 ;
_______________________________________________
Now find f (g(-5) to get the answer; that is f(23); 
_______________________________________________
  Find f(23).  f(x) = -2x </span>− 7 .  
 
  f(23) = (-2*23) − 7 = -46 <span>− </span>7 = -53 ; which is "Answer choice: [A]" .

What is the value of 9(n+2)−5n for n=14?<br> 3<br> 9<br> 10<br> 19
Murrr4er [49]
If you want to know the value of a  function, you need to substitute the variable (here n) for the value:

so in the function

9(n+2)−5n

we substitute n with 14:

<span>9(14+2)−5*14

first calculate the inside of the bracket:

</span>
<span>9*16−5*14

9 times 16 is 144

144-5*14

5*14 is 70, so we have

144-70=74

so the answer should actually be 74!

Perhaps you mistyped the questions? can you check it again, please?
