Answer:
2x+y
Step-by-step explanation:
x-(-x)+y the subtraction sign and negative x cancel and makes the x positive
x+x=y
2x+y
Answer: 62.5%
Step-by-step explanation:
Given
Ms. Savage ate of her lunch
i.e. she ate 5 parts of lunch out of 8
In percentage, it is expressed as
Answer: y=-5x-36
Step-by-step explanation:
In order for two lines to be parallel they need to have the same slope. so the slope (m) of the new line needs to be -5.
slope(m) =-5
and the point (-8,4) is given to us. we can create a new equation for a line using the point slope formula because we have a slope (m=-5) and a point (-8,4)
point slope formula: y-y1=m(x-x1)
y-4=-5(x--8)
simplify and pay attention to negative signs
y-4=-5(x+8)
y-4=-5x-40
y=-5x-36

The answer to this question is 2.1
Answer:
26 cm^3
Step-by-step explanation:
volume of cylinder = (pi)r^2h
volume of cone = (1/3)(pi)r^2h
Since (pi)r^2h = volume of cylinder, then you get
volume of cone = (1/3)(volume of cylinder) = (volume of cylinder)/3
The difference between the volume of a cylinder and the volume of a cone is that a cone with the same radius and height has 1/3 the volume of the cylinder.
If you know the volume of a cylinder, then the volume of a cone with the same radius and height is 1/3 the volume of the cylinder, or simply, divide the volume of the cylinder by 3.
volume of cylinder = 78 cm^3
volume of cone = (78 cm^3)/3 = 26 cm^3
