Answer 2

To evaluate the expression 1/3x³ + y² when x = -3 and y = -2/3, we can substitute these values into the expression and perform the calculations.

Substituting x = -3 and y = -2/3 into the expression:

1/3(-3)³ + (-2/3)²

Simplifying:

1/3(-27) + (-2/3)²

-9 + (-2/3)²

-9 + (-2/3)(-2/3)

-9 + 4/9

To add the fractions, we need a common denominator, which is 9.

(-9)(9/9) + 4/9

-81/9 + 4/9

Combining the fractions:

(-81 + 4)/9

-77/9

Therefore, when x = -3 and y = -2/3, the expression 1/3x³ + y² evaluates to -77/9.
