2 x 2 = 4 x 60 = 240
2 x 4 x 4 2 x 2 x 8
1 x 4, 2 x 2, 4 x 1 = 4
PQR P=2 Q=4 R=5 2 x 4 x 5 = 40
y varies directly as x y=kx, where k is any constant y = 4 when x=-2 4 = k (-2) 4 =-2k k=-2 Therefore, y=-2x When x=30 y = -2(30) = -60
4
-2
2 x 2 = 4 x 60 = 240
x = -2
4
4
-(2)Squared = 4
-x -2 = 2 so -x = 2+2 = 4 and so x = -4
4 + x = 2x --> 4 = 2x - x --> 4 = x: x = 4
No, it is not.
-1/2
4 + x = 2x Subtract 'x' from both sides 4 = 2x - x x = 4 Verification 4 + 4 = 2(4) 8 = 2 x 4 = 8 True!!!!!
