Answer:

X= 5 ( 2 + Y )❤️

Step-by-step explanation:

  1. X = 5y + 10
  • X= 5( Y + 2 )

  1. 2x-10y= 20
  • 2( X - 5y ) = 20
  • (x-5y ) = 20/2
  • X - 5y = 10
  • X= 10 + 5y
  • X = 5 ( 2 + Y )

What are the domain and range of each relation?
torisob [31]

Order pairs  given coordinates on the graph: {(−3, 1), (−3, -4), (−1, 1), (1, -1), (4,4)}.


We need to find the domain and range.


<em>Domain of the order pairs are x values of each coordinate and range is the y values of each given coordinate.</em>


Each first value of order pair are the x values and each second value of each order pair are the y values.


In the given coordinates on the graph (−3, 1), (−3, -4), (−1, 1), (1, -1), (4,4), we can see first values are { -3,-1, 1, 4}


and we can see second values are { -4, -1, 1, 4}.

<h3>Therefore, Domain : { -3,-1, 1, 4} and </h3><h3>Range : { -4, -1, 1, 4}</h3>
