volume = π x r^2 x h
diameter = 20, radius = 20/2 = 10
10^2 = 100
100 * 5 = 500
volume = 500π cubic cm
Look at point (-3,-1) on triangle I. The corresponding point on triangle II is (-4, 1). X moved 1 to the left, so a -1 will go in the box for x. Y moved up 2, so a 2 will go in the box for y.

Answer:
b
Step-by-step explanation:
Answer:
Simplifying
5(x + 9) = 5x + 45
Reorder the terms:
5(9 + x) = 5x + 45
(9 * 5 + x * 5) = 5x + 45
(45 + 5x) = 5x + 45
Reorder the terms:
45 + 5x = 45 + 5x
Add '-45' to each side of the equation.
45 + -45 + 5x = 45 + -45 + 5x
Combine like terms: 45 + -45 = 0
0 + 5x = 45 + -45 + 5x
5x = 45 + -45 + 5x
Combine like terms: 45 + -45 = 0
5x = 0 + 5x
5x = 5x
Add '-5x' to each side of the equation.
5x + -5x = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 0
Solving
0 = 0
