Choose the equation of the horizontal line that passes through the point (−8, −7). a. y = −8 b. y = −7 c. x = −8 d. x = −7

Horizontal line is y=a, where a is a constant (number).

We need to choose equation this type.

y= - 7, means that for all values of x y=7.

So, answer is

B. y= - 7

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
