The value of the x-intercept for the graph 2x -5y = 30 is

(15, 0)

Step-by-step explanation:

since we're looking for the x-intercept of the equation, we have to set y = 0.

2x - 5y = 30

2x - 5(0) = 30

2x = 30

now divide both sides by 2 to get x alone

2x/2 = x

30/2 = 15

so the x-intercept is (15, 0)

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

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
