Solve the equation 3x2 + 19x + 9 = 0 to the nearest tenth.

Without multiplying, tell which product is larger and why. 5 × 1/3 or 5 × 2/3 a)5 × 1/3 because 1/3 is less than 2/3 b) 5 × 1/3 because 1/3 is greater than 2/3 c) 5 × 2/3 because 1/3 is less than 23 d) 5 × 23 because 1/3 is greater than 2/3

Solve the system of equations. y=3x-1 and y=-2x+9. show work
