Question

evaluate rational expression using the indicated values for the variables.5x^2/6y.a.when x=4 and y=10 b. when x=0 and y=11

Answer 1

The given expression is,

`(5x^2)/(6y)\text{ --(1)}`

a)

Put x=4 and y=10 in expression (1) and simplify.

`(5*4^2)/(6*10)=(5*16)/(60)=(80)/(60)=(4)/(3)`

Therefore, when x=4 and y=10, the value of the given rational expression is 4/3.

b)

Put x=0 and y=11 in expression (1) and simplify.

`(5*0)/(6*11)=0`

Therefore, when x=0 and y=11, the value of the given rational expression is 0.
