Which of the ordered pairs form (x, y) is a solution of this equation? 3x + 2y = 6 A. (4, -3)
B. None are solutions.
C. (-2, 0)
D. (8, -5)

A

Step-by-step explanation:

3*4 +2*(-3)=6

12-6=6

6=6 which is true

A. (4, -3)

Step-by-step explanation:

substitute x and y for 4 and -3 so the equation would be 3(4) + 2(-3) = 6 and 4 times 3 = 12 and 2 times -3 = -6 so then the equation would be 12 + (-6) = 6 or 12 - 6 = 6. Therefore, the answer A is correct

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
