Plot three points that are solutions to the equation 2x-y=4

(0,-4)  (1,-2)  (2,0)

Step-by-step explanation:

2x-y = 4

solve for y

subtract 2x from each side

-y = -2x+4

multiply by -1

y =2x-4

three points

let x= 0

y = -4

(0,-4)

let x = 1

y = 2(1) -4

y = -2

(1,-2)

let x =2

y = 2(2) -4

y =4-4

(2,0)

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
