Answer:
Step-by-step explanation:
Given
Represent the volume of the cylinder with V1 and the volume of the sphere with V2
So, from the first statement: we have:
and
To solve for 
, we simply substitute 
for 
in
Hence, the volume of the sphere is 
Answer:
8 months and $320
Step-by-step explanation:
To find when 30m + 80 = 40m, isolate m.
30m + 80 = 40m
Subtract 40m from both sides.
-10m + 80 = 0
Subtract 80 from both sides.
-10m = -80
Divide both sides by -10
m = 8
To find the cost, substitute 8 as m in one of the equations.
40(8) = 320
Answer:......................................................
Step-by-step explanation:
Slope is how much a graph increases or decreases and is found by counting to the right or left (x axis) and up or down (y axis)
intercepts are determined where points are on the y or x axis and are y = mx + B (it is b)
linear functions and equations can be graphs by y = mx + b or y = mx
