Answer:
A) 1/12 lb.
.. (1 2/3)/20 = 1/20 + (2/3)*(1/20)
.. = 1/20 + 1/30
.. = 3/60 + 2/60
.. = 5/60 = 1/12
(1,-5)(3,-17)
slope = (-17 - (-5) / (3 - 1) = - 12/2 = - 6
y = mx + b
slope(m) = -6
use either of ur points...(1,-5)...x = 1 and y = -5
now we sub and find b, the y int
-5 = -6(1) + b
-5 = -6 + b
-5 + 6 = b
1 = b
so ur equation is : y = -6x + 1....or 6x + y = 1
Hope this helps!

Step-by-step explanation:
Answer: 28.8%
Step-by-step explanation:
First find out what her speed is:
Speed = Distance / Time
= 50 / 45
= 1.11 meters/second
Now her speed is:
= 50 / 35
= 1.43 meters/ second
The percentage increase in her speed is:
= (New speed - Old speed) / Old speed
= (1.43 - 1.11) / 1.11
= 0.288
= 28.8%
