Answer 1

The given expression is

`(13y+5)/(y^2-3y-10)`

The value of y is 9, then

Substitute y by 9 in the expression

`(13(9)+5)/((9^2)-3(9)-10)`

Simplify up and down

`(117+5)/(81-27-10)=(122)/(44)`

Divide up and down by t to get the simplest fraction

`((122)/(2))/((44)/(2))=(61)/(22)`

The value of the rational expression is 61/22 = 2 17/22 (mixed number)

You can write it as an improper fraction of 61/22

You can write it as a mixed number 2 17/22
