The saying "A picture is worth a thousand words" comes to mind here. You can list all of the possible points in a solution region, or you can list a few points to give the general pattern. Though this method requires a bit more work than simply graphing and showing the solution shaded region. A visual is often more efficient at conveying a message especially to those who aren't proficient with algebra. I'm sure there are other reasons why graphs are the better choice, but that's all I could think of really.
Answer:
C. 2448π units³
Step-by-step explanation:
V = π·r²·h
= π·12²×17
= 144×17·π
= 2448π units³
The answer is 42.3
Step by Step:
Let our variable be n, standing for number.
3.6(x) + 4.5(y) = n
3.6(3) + 4.5(7) = n
10.8 + 31.5 = n
n = 42.3
We have to find the slope of the line that passes through this points:
p1(-2,15), p2(-8,-5)
the slope of a line through two points is calculated like this:
m = (y2 - y1)/(x2 - x1)
where x1,y1,x2,y2 are the coordinates of the two points, so we have:
m = (-5 - 15)/(-8 - (-2))
m = (-20)/(-8 + 2)
m = -20/-6
m = 10/3
that is the line slope
