V=(pi)(2r^2)(h)
V=4(pi)(r^2)(h)
V=4(100 aka the old volume)
V=400cm^3
Find 2 coordinates on the graph : (0, -20) and (10, 10)
Slope = (10 - (-20) ) / (10 - 0) = 30/10 = 3
Slope = 3
y-intercept = (0, - 20)
Equation : y = 3x - 20
Since the right hand side is shaded, the equation is y > 3x - 20.
Simplification = 3.5x + 2.5x
Result = 6x
1/3 of 6=2(4 left)
3/8 of 4=1 1/2
1 1/2 yards left
Answer:
infinite solutions
Step-by-step explanation:
3(n+6)≥3n+8
3n+18≥3n+8 (distributive property)
18≥8 (subtracted 3n from both sides)
this will always be true so there are infinite solutions
