What is the vertex of the graph of the function below?

y=x^2-4x+3

Write the expression 40w - 16, as a product with a whole number greater then one.

Graph the inequality: - 2x - y < 3

Solve the system of equations. 5x + y = 9 3x + 2y = 4 (-2, 5) (1, 4) (2, - 1) (4, - 4)

An integer is 15 more than 2 tomes another. If the product of two integers is - 27 then find the integers
