The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Which letters from the table represent like terms? a and b b and c a and d b and d

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.
