Answer:
Step-by-step explanation:
Plot the point (4, 0) (the x-intercept) and then the point (0, -3) (the y-intercept). Draw a straight line through these two points.
A point on the edge of the roller travels the circumference of the roller in 1 revolution, so that its linear velocity is
(10 rev/s) * (2*(14.25 cm)*pi cm/rev) = 285 pi cm/s
or about 895.4 cm/s.
7(x - 4) - 3(x + 5)
Distribute the 7 and 3
7x - 28 - 3x - 15
4x - 43
