Answer:
14
Step-by-step explanation:
14 is the correct answer. When you use x = 3 and y = 5 in the given expressions, 3x2 - 2y = 3(3)2 - 2(5) = 27 - 10 = 17 and 2x2 - 3y = 2(3)2 - 3(5) = 18 - 15 = 3. Then subtract 3 from 17 to get 14.
Answer:

Step-by-step explanation:
y = mx + b
3 = 1(5) + b
-2 = b
y = x-2
