I believe x is 0 because if we assume y and x are 0 then 0=0 and 0= 5 x 0
It’s A since 7/8 x (-16) is -14 then -14 x (-7) is 98 and 98 x (-1/14) is -98/14 which gets -7
Answer:
According to the passage, we have the next equation:

where "K" is a proportional constant
Leaving at the end with the next equation:

Integrating the equation, we have:

where "C" is a constant
Then, we have the 2 conditions for the problem:
1) t=0 → r=10
Replacing in the equation, we have C = 10
2) t=5 → r=8
Replacing in the equation, we have K = -0.4
Finally, the time which the snowball will be completely melted will be when r = 0. So replacing in the equation

t = 25 minutes
Answer:
y = 2x -8
