Answer:
B and c
Step-by-step explanation:
Y=5*9-4
y=45-4
y=41
y=5*(-6)-4
y=-30-4
y=-34
y(41,-34)
Remove the parenthesis
4m+3m-2m-2
Combine like terms add 4 to 3m =7 subtract 7 from 2 = 5m
Drop the 2 so your answer would be
B
5m-2
<span> D) Train A by a factor of 1.1
</span>Train A: <span>17/35</span><span> = 34.6</span>
<span>Train B: </span>Rate<span> is the </span>slope<span> of the </span>equation, 31.35
Thus,<span>34.6/31.35</span><span> = 1.1036</span>
Point C, since pi=around 3.14
Hope that helps :)
