Question

What is 9x2y-3 if x = 5 and y = 3.

Answer 1

To evaluate 9x2y-3 when x = 5 and y = 3, substitute the given values into the expression to get 672.

Step-by-step explanation:

To evaluate the expression 9x2y-3 when x = 5 and y = 3, we substitute the given values of x and y into the expression.

Substituting x = 5 and y = 3, we get:

9(5)^2(3) - 3 = 9(25)(3) - 3 = 675 - 3 = 672

Therefore, when x = 5 and y = 3, 9x2y-3 equals 672.
