3. solve the system using substitution (1 point) y = 8 - x 7 = 2 - y (a). (5, 13) (b). (13, -5) (c). (3, 5) (d). (21, -13)

Which table represents a linear function? i'll give brainliest to first answer ^'^

Find the least common multiple of the expressions: 1. 3x^2, 6x - 18 2. 5x, 5x(x +2) 3. x^2 - 9, x + 3 4. x^2 - 3x - 10, x + 2 explain if possible

Subtract and simplify. (-y^2 – 4y - 8) – (-4y^2 – 6y + 3) show how you got the answer if your answer is right i will mark you
