6. Julie is asked to solve the system below by elimination. Which of the following steps would be the best way to begin?
2x + y = -3 ?
3x - 2y = 2

A. Multiply O by 2 and multiply by 3
B. Multiply by 2
C. Multiply O by 2
D. Multiply by 2 and multiply O by -2

Write a real-world solution that can be represented by the equation y = 7x be sure to explain what the variables represented in the solution

Solve the system by the elimination method. 3x - 2y - 7 = 0 5x + y - 3 = 0 to eliminate y, the lcm is 2. which of the following is the resulting equations? 1.3x - 2y - 7 = 0 5x + y - 3 = 0 2.3x - 2y - 7 = 0 -10x - 2y + 6 = 0 3.3x - 2y - 7 = 0 10x + 2y - 6 = 0

These tables represent a quadratic function with a vertex at (0, -1). what is the average rate of change for the interval from x = 9 to x = 10?
