One reservoir has 380m3 of water, and another has 1500m3 of water. Every hour 80m3 of water are added to the first and 60m3 are taken out of the second. In how many hours will the amount of water in both the reservoirs be equal? Write each as a separate equation and graph them.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

the second option

step-by-step explanation:

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
