Yes sure thing, i would love to help you.
This can be treated as a work problem and we can solve it as follows:
Harland working alone = 15 minutes
Trudy scatters the leaves + Harland rakes = 20 minutes
We set scattering as a negative value.
1/15 - 1/x = 1/20
x = 60 minutes for Trudy to scatter the leaves alone
Answer:
The graph should have a y-intercept of -8
Step-by-step explanation:
It seems like your question is incomplete, i can't see any options of graphs.
Could you send a picture?
~ : to represent sign of proportionality
y ~ 1/x
y = k/x
x=20, y=4
4 = k/20
k = (20×4) = 80
y = 80/x
x=35, y = 80/35 = 2.29
The proportional constant k = 80
The function is: y = k/x
The new value of y is: 2.29
Hope it helped!
