Respuesta :

To evaluate this expression you just have to substitue the value that is given.

so since we know m=2 x=7 y=5

and the expression is given mx-y

plug these values in as 2(7)-5 = 14-5 = 9

Answer:

The value of the expression for m=2, x=7, and y=5 is 9.

Step-by-step explanation:

Consider the provided expression.

[tex]mx-y[/tex]

We need to find the value of the expression, for m=2, x=7, and y=5.

Substitute the respective values in the above expression as shown:

[tex](2)(7)-(5)[/tex]

[tex]14-(5)[/tex]

[tex]14-5[/tex]

[tex]9[/tex]

Hence, the value of the expression for m=2, x=7, and y=5 is 9.
