Answer:
8 hours
Step-by-step explanation:
it's increasing by 6 so at the end there's a reminder of 2.
Answer:
y = 1/2x + 2
Step-by-step explanation:
slope:
6 - 3 / 8 - 2 = 3 / 6 = 1/2
start by putting it in point slope form and then simplify it to slope intercept form:
y - 3 = 1/2(x - 2)
y - 3 = 1/2x - 1
y = 1/2x + 2
If you subtract this problem the answer would be 13/28
