Cf=cold faucet rate
hf=hot faucet rate
cf*18min=1 tub
(cf+hf)*8min=1 tub
cf+hf=1tub/8min
cf=1tub/18min
hf=(1/8-1/18)tubs per minute
hf=5/72
It takes 14.4 minutes.

The coefficients are 2, -90, -40
Answer:10
Step-by-step explanation:
Answer:
4092
Step-by-step explanation:
The n th term of a geometric series is
= a
where a is the first term and r the common ratio
4
← is the n th term
with a = 4 and r = 2
The sum to n terms of an arithmetic series is
= 
, thus
= 
= 4(1024 - 1) = 4 × 1023 = 4092
All you need to do to find the slope here is put it into y = mx + b format.
5y + 6x - 2 = 0
the goal is to get the y alone, so...
5y = 2 - 6x
divide both sides by 5
y = 2/5 - (6/5)x
then, just to be clearer for y = mx + b ...... y = (-6/5)x + (2/5)
the slope should be (-6/5)
