In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?

Which expression is equivalent to 3^3 + 2^2?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
