If the area square 3 is 80 cm^2 and the area of square 2 is 100 cm^2, what is the area of square 1

The graph of which equation includes the points (0, 10) and (10, 11)? y = 10x + 11 y = x + 10 y= 1/10x + 10 y = 1/10x + 11

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2

How many real-number solutions does the equation have? -4x^2 + 10x + 6 = 0 a. no solutions b. two solutions c. infinitely many solutions d. one solution
