A block of ice weighing 50 kilograms begins to melt. Each hour the block of ice loses 10% of its weight. Let W be the weight in kilograms after melting for t hours. Describe the relationship between W and t?

The relationship between W and T is that T is the amount of hours the block is melting for, and T is the weight after W hours. As you can see, they are proportionate.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
