Answer:
y = -4/3x +4
Step-by-step explanation:
6y + 8x = 24
Subtract 8x from each side
6y + 8x-8x = -8x+24
6y = -8x+24
Divide each side by 6
6y/6 = -8x/6 +24/6
y = -4/3x +4
Answer: The required system of equations representing the given situation is
![y=1+0.5x\\\\y=3+0.25x](https://tex.z-dn.net/?f=y%3D1%2B0.5x%5C%5C%5C%5Cy%3D3%2B0.25x)
Step-by-step explanation: Given that Sam needs to make a long-distance call from a pay phone.
We are to write a system to represent the situation.
Let x represent the number of minutes Sam talked on the phone and y represents the total amount that he paid for the call.
According to the given information,
with prepaid phone card, Sam will be charged $1.00 to connect and $0.50 per minute.
So, the equation representing this situation is
![y=1+0.5x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)](https://tex.z-dn.net/?f=y%3D1%2B0.5x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~%28i%29)
Also, if Sam places a collect call with the operator he will be charged $3.00 to connect and $0.25 per minute.
So, the equation representing this situation is
![y=3+0.25x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)](https://tex.z-dn.net/?f=y%3D3%2B0.25x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~%28ii%29)
Thus, the required system of equations representing the given situation is
![y=1+0.5x\\\\y=3+0.25x](https://tex.z-dn.net/?f=y%3D1%2B0.5x%5C%5C%5C%5Cy%3D3%2B0.25x)
