WebThe reason is that y doesn't vary by the same proportion that x does (because of the constant, 24). In your equation, "y = -4x/3 + 6", for x = 1, 2, and 3, you get y = 4 2/3, 3 1/3, and 2. For x = -1, -2, and -3, y is 7 1/3, 8 2/3, and 10. Notice that as x doubles and triples, y does not do the same, because of the constant 6. Web6 apr. 2024 · Since y is the mean proportional between x and z. Therefore, y²=xz. Now we have to prove that xy + yz is mean proportional between x² + y² and y² + z². Hence proved
