Question

What is the value of the expression 4x−y2y+x when x = 3 and y = 3? a. −3 b. 1 c.9 d.18 100 pts if answered correctly and properly

Answer 1

4x-y2y+x

4(3) -[(3)2(3)]+3

12-[18]+3

12-18+3

-6+3

=-3

Answer 2

C. 9

Explanation:

Plug in 3 for both x and y .

4x - y = 4(3) - (3) = (4 * 3) - 3 = (12) - 3 = 9

2y + x = 2(3) + (3) = (2 * 3) + 3 = 6 + 3 = 9

C. 9 is your answer.
