Which of the following functions have the ordered pair (2, 5) as a solution?4 + x = yy = 2 x7 - x = yx + 3 = y

Sagot :

Given

The ordered pair (2,5).

To find which of the functions have the ordered pair as a solution.

Explanation:

It is given that,

The ordered pair (2,5).

Then, put x=2, and y=5 in the function x+3=y.

That implies,

[tex]\begin{gathered} 2+3=5 \\ 5=5 \end{gathered}[/tex]

Hence, the ordered pair (2,5) is a solution of the function x+3=y.

Also, substitute x=2, y=5 in the function 7-x=y.

That implies,

[tex]\begin{gathered} 7-2=5 \\ 5=5 \end{gathered}[/tex]

Hence, the ordered pair (2,5) is a solution of the function 7-x=y.
