Identify and verify the values of x and y that simultaneously satisfy the pair of equations y = 2x + 6 and y = –4x – 6 by graphing. *

y = 2x + 6 is slope 2 and y-intercept (0,6)

y = –4x – 6 is slope -4 and y- intercept (0,6)

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
