Graph x^3-x^2-2x=0 what are the solutions of the equation
Aleks [24]
X^3 - x^2 - 2x = 0
x ( x^2 - x - 2 ) = 0
x (x-2) (x+1) = 0
x = 0
x-2 = 0 --> x = 2
x+1 = 0 --> x = -1

x = 0, x = 2, x = -1

Which of the following represents an equation of a line parallel to one whose equation is 2x + 8x = 18
Naya [18.7K]

Answer:

y=-4x+3

Step-by-step explanation:

it does not show the equations that are following

but the main thing you need to know is that when two lines are parallel they have the same slope

and do you mean 2x+8y=18 not x?

edit:

answer choices: y=-4x+3, y=8x-2, y=4x+7, y=-8x+9

2y+8x=18

first change that equation to slope intercept form to find the slope

2y = -8x+18 -> y = -4x+9

slope is -4

so the answer is y=-4x+3 because it also has a slope of -4

a circular frame that is 3-inches wide surrounds the mirror what I the combined area in square inches of the circular mirror and
Tcecarenko [31]
Assuming the frame is a perfect circle
and 3 inches wide indicates the diameter


area of a circle=pi times radius^2

diameter=2 times radius
radius=1/2 diameter
diameter=3
radius=1/2 times 3
radius=3/2=1.5

area=pi times 1.5^2=2.25
pi is aprox 3.14 so
2.25 times 3.14=7.065 square inches


the answer is 2.25π square inches or 7.065 square inches
