Answer:
Neon: 0
Oxide: -2
Copper: 2
Tin: 0
Step-by-step explanation: To solve you must add/subtract the numbers to get the charge, for example if its -30 charge from electrons and 10 charge from protons, -30 + 10 = -20 therefore the charge is -20
Divide the first one by the second and the answer will be B.
Function A is linear
y = 5/3x + 0
let me know if this is incorrect
X is radical 3
y is 2 radical 3
