Question

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

Answer 1

ANSWER

-9/7

EXPLANATION

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

$\frac{(-1)^2\cdot9}{-7}=\frac{1\cdot9}{-7}=-\frac{9}{7}$

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