Answer:

1.

a. a = kb

b. p = k(½q) or p = q/2

c. C = kd

d. d = kt²

e. B = kW

2.

a. constant of variation: ¾

b. constant of variation: ⅓ not sure nakalimutan ko na

c. constant of variation: 4

3.

a. y = kx; y = 8; x = 4; k =?

Substitute:

=> 8 = k4

=> 8/4 = k4/4

=> k = 2

y = kx; x = 10; k = 2; y = ?

Substitute:

=> y = 2(10)

=> y = 20

-------------------------------------------------------

b. y = kx; y = ½; x = 4; k = ?

Substitute:

=> ½ = k4

=> (½)/4 = k4/4

=> (½)(¼) = k

=> k = ⅛

y = kx; x = -8; k = ⅛; y = ?

Substitute:

=> y = (⅛)(-8)

=> y = -8/8

=> y = -1
