Question

1. y varies directly as the square of x. When x = 5, y = 100. Find y when x = 6.

y = 105
y = 120
y = 144
y = 150

2. y varies inversely as three times x. When x = 6, y = 4. Find x when y = 8.

x = 1
x = 2
x = 3
x = 4

3. y varies jointly with p and q. When p = 5 and q = 2, y = 80. Find y when p = 4 and q = 5.

y = 20
y = 120
y = 160
y = 240
