Question

Find the value of this expression if x=-1 and y=9X^2y/-7

Answer 1

-9/7

Step-by-step explanation

To find the value of the expression we have to replace x with -1 and y with 9 and solve,

`((-1)^2\cdot9)/(-7)=(1\cdot9)/(-7)=-(9)/(7)`

Hence, the value of the expression when x = -1 and y = 9 is -9/7.
