Answer:
1. k = 6
2. k = 5
3. k = 3/45
4. k = 2
Step-by-step explanation:
1. z varies jointly as x and y and z = 36 when x = 3 and y = 2
z = kxy
z = 36, x = 3, y = 2
36 = k • 3 • 2
36 = k • 6
36/6 = k
6 = k
=====
2. z varies jointly as x and y. z = 60 when x = 3 and y = 4
z = kxy
z = 60, x = 3, y = 4
60 = k • 3 • 4
60 = k • 12
60/12 = k
5 = k
=====
3. z varies jointly as x and y. z = 3 when x = 3 and y = 15
z = kxy
z = 3, x = 3, y = 15
3 = k • 3 • 15
3 = k • 45
3/45 = k
=====
4. z varies jointly as x and y and z = 60 when x = 5 and y = 6
z = kxy
60 = k • 5 • 6
60 = k • 30
60/30 = k
2 = k
