Answer: -3 = k


Step-by-step explanation: y/x = k is the equation.

Okay so you plug in y into that equation and x also. You should have the equation -9/3 = k. All you do is solve! You should get -3=k. I hope this helped! :D

Can anyone help me with this question please?
Oxana [17]

Answer:

y=35z+20

Step-by-step explanation:

Y is the total cost, so it goes on the outside. 35z represents the months of service because you multiply 35 by however many months there are (for example, if you had 3 months, you'd have $35 3 times). Finally, the $20 is tacked onto the end because that's the initial payment to open an account
