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?

m a t h w a y. c o m

step-by-step explanation:

answer: i think it is (1,-2)

i'm a sophomore in connections, i'd recommend checking on jishka.com they have a large range of questions and answers from our school.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
