That is not correct. I will help you. Begin by subtracting the 9x from both sides, like this: 9x - 9x + 2y = 6 - 9x. That simplifies to 2y = -9x + 6. Now divide both sides by 2 to get y all alone, like this:
. That reduces down to
. That is slope-intercept form. y = mx + b.
The solution would be like this for this specific problem:
Volume of a cylinder = pi * r^2 * h
Volume of a cone = 1/3 * pi * r^2 * h
Total Height = 47
Height of the cone = 12
Height of the cylinder = 35
If the top half is filled with sand, then:
volume (sand) = pi * 4^2 * 36
volume (cone) = 1/3 * pi * 4^2 * 12
Total volume = 1960.353816 cubic millimeters
353816 / (10 * pi) = 62.4 seconds.
It will take 62.4 seconds until all of the sand has dripped to the bottom of the hourglass.
Answer: They traveled 405 Miles
Step-by-step explanation:
Trust me! The equation is..
5+4(45)
9(45)
405
Answer:
y=-3x+3..........(1)
6x+2y=6
putting value of y
6x+2(-3x+3)=6
6x-6x+6=6
o=0
