The multiplier is (1/4) or .25
y=19x+9 would be the rule
Answer:
<u>The equations for each function:</u>
- A(t) = 60 - 6t
- B(t) = 42 - 3t
<em>The lines plotted, see attached</em>
<u>The point at which both the snowmen have same height:</u>
- 60 - 6t = 42 - 3t
- 6t - 3t = 60 - 42
- 3t = 18
- t = 6
<u>The required interval is </u>
From the diagram you can see that for all

This means that function is constant on the interval 
Answer: correct choice is C.
