Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (4, 3) and (x₂, y₂ ) = (- 2, - 5)
m = 
= 
=
It would be 81 or you can do 81/8 = 9
To determine how long it will take to fill the empty tank, you will first find the capacity of the tank (the volume) and then divide this into groups of 750 cm^3. Every group will be one minute.
V =lwh
20 x 20 x 15
V = 6000 cm^3
6000 cm^3/750 cm^3 = 8
It will take 8 minutes to fill the empty tank.
Answer:
yes,c=2.
Step-by-step explanation:
7.8c+3.4=19
7.8c=19-3.4
7.8c=15.6
c=15.6/7.8
c=2
