Answer: 6 m
Identify the given information.
w = 1500 J
f = 250 N
Choose which formula you should use. In this case, you are finding the distance.
d = w/f
Substitute and solve.
d = 1500 J/250 N
d = 6 m
The answer is 2. Hope this helps!
3v-9v is -6v
-6v=30 Divide each side by -6
v=-5
To check: substitute -5 back into the equation wherever you see v
3(-5)-9(-5)=30
-15+45=30
30=30
F(x) = -2.5x + 135...where x is the number of weeks, and f(x) = total weight
