Answer:

{x,y} = {5,8}

Step-by-step explanation:

 [1]           7x-3y+5=16

 [2]           4y=3x+17

 

  [1]    7x - 3y = 11

  [2]    -3x + 4y = 17

// Solve equation [2] for the variable  y  

 

 [2]    4y = 3x + 17

 [2]    y = 3x/4 + 17/4

// Plug this in for variable  y  in equation [1]

  [1]    7x - 3•(3x/4+17/4) = 11

  [1]    19x/4 = 95/4

  [1]    19x = 95

// Solve equation [1] for the variable  x  

  [1]    19x = 95  

  [1]    x = 5  

// By now we know this much :

   x = 5

   y = 3x/4+17/4

// Use the  x  value to solve for  y  

   y = (3/4)(5)+17/4 = 8

Which rule describes a translation that is 3 units to the right and 5 units down?
AysviL [449]

For this case we have the following functions transformation:


Vertical translations:

Suppose that k> 0

To graph y = f (x) -k, move the graph of f(x) k units down


Horizontal translations:

Suppose that h> 0

To graph y = f (x-h), move the graph of f(x) h units to the right.

Applying the transformations to an ordered pair we have:

(x, y) ------------------> (x-3, y-5) ----------------- -> (x ', y')


Answer:

The rule that describes a translation that is 3 units to the right and 5 units down is:

(x, y) ------------------> (x-3, y-5) ----------------- -> (x ', y')

Can a function have a y-value with more than one x value why or why not ?
jekas [21]
No because x can only repeat two times. After that it is no longer a proper function
