3k-1=k+2 2k=3 k=3/2=1.5
k=2.
5k + 2 = -2 Therefore, 5k = -4 k = -4/5 k = -0.8
k/2 -k/5 -k/6 = 2 Multply all terms by 30: 15k -6k -5k = 60 4k = 60 k = 15
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
1 k equals 1000 2 k equals 2000 and so on
2+2+7=11 K?
k = 2 and 2 < 12
3k-1=k+2 2k=3 k=3/2=1.5
j=-3 and k=2
50
neg(-k) + neg(-k) = k + k = 2k = 4
k=2.
k = 2
k=-2
5k + 2 = -2 Therefore, 5k = -4 k = -4/5 k = -0.8
k/2 -k/5 -k/6 = 2 Multply all terms by 30: 15k -6k -5k = 60 4k = 60 k = 15
